关于IDEA生成class文件的问题? 1C
IDEA配置的环境是JDK8,生成了字节码文件,在linux jdk8的环境上运行没有问题,
在linux jdk7的环境上运行直接报错。整个字节码文件 没有不兼容的地方,这是为什么?

3个回答

报什么错误你没有贴出来怎么看?

碎破星空 错误我都忘记了,就是服务起不起来。后来我用Myeclispe 也是JDK8环境生成了class文件,丢上去启动就好了,所以才问IDEA的字节码文件是不是有问题。

你把环境配置成JDK7,生成了字节码文件,再在linux jdk7的环境上运行试试

我个人认为jdk7与jdk8的编码应该一样,可能你引用的jar包对jdk1.7与jdk1.8兼容性有问题

碎破星空 jar包没有问题,因为用MyE的话是可以的。IDEA生成的class就是不行。

IntelliJ IDEA编译生成class文件运行的问题
![图片说明](https://img-ask.csdn.net/upload/201512/13/1450020227_105892.jpg) 如图,我在src目录下存放源代码,然后resources目录下存放要读取的文件,由于默认的当前路径是Module目录,所以我的文件访问路径“resources/test.txt” 这个程序运行没有问题,但是如果我想运行编译后的程序即class文件,这个目录是错误的 ![图片说明](https://img-ask.csdn.net/upload/201512/13/1450020530_473983.png) 有没有一种一次设置,问题全部解决的方法 我感觉这样不符合idea的精致啊!
webservice 通过wsdl生成客户端代码 对象属性的顺序改变
IDEA 写一个webservice 挂在下面的ip String address = "http://10.xx.xxx.xxx:9000/GetInfo"; Endpoint.publish(address, implementor); 然后浏览器输入这个ip,下载.wsdl文件 然后根据wsdl文件生成webservice客户端的时候,对象属性的顺序变了 比如 写Webservice的时候用到一个对象student 属性依次为Name,Class,ID 当用wsdl文件生成客户端的时候 代码里面的Student对象中的属性顺序就变了 变成了Class,ID,Name 目测是按照abc的顺序 由于一些奇葩的原因 希望这个对象的属性的顺序不变 不知道能不能实现 可能描述的不太清楚.... 希望大神们帮忙看看
IDEA环境Springboot2.2.1进行Web开发,自定义pesonal.yml文件读取不到value值
先看下文件位置: ![图片说明](https://img-ask.csdn.net/upload/202001/22/1579675010_950804.png) 文件内容如下: ```yaml jwt: # 加密私钥 secret: bensu[sentiment] # header名称 header: token # 有效时长7天(7*24*60*60) expire: 604800 ``` 绑定实体类代码如下: ```java @Component @PropertySource("classpath:personal.yml") @ConfigurationProperties(prefix = "jwt") public class TokenDomain { // header名称 @Value(value = "${header}") private String header; // 密钥 @Value(value = "${secret}") private String secret; // 有效时长 @Value(value = "${expire}") private long expire; public String getHeader() { return header; } public void setHeader(String header) { this.header = header; } public String getSecret() { return secret; } public void setSecret(String secret) { this.secret = secret; } public long getExpire() { return expire; } public void setExpire(long expire) { this.expire = expire; } } ``` 调用该实体类代码如下: ```java @Autowired private TokenDomain tokenDomain; /** * 根据身份ID标识,生成Token * @param userId 根据身份ID标识 * @param pwd 密码 * @return Token 字串 */ public String createToken(String userId,String pwd){ //过期时间,精确到毫秒 Date expireDate = new Date(new Date().getTime() + tokenDomain.getExpire()); // 生成token字串 String token =Jwts.builder() .setHeaderParam("typ","JWT") .setHeaderParam("alg","HS256") .claim("userId",userId) .claim("pwd",pwd) .setSubject(userId+pwd) .setIssuedAt(new Date()) .setExpiration(expireDate) .signWith(SignatureAlgorithm.ES512, tokenDomain.getSecret()) .compact(); return token; } ``` 实体类在Spring测试类中可正常读取: ```java @Autowired TokenDomain token; @Test void getPersonal(){ System.out.println(token); System.out.println(token.getHeader()); System.out.println(token.getSecret()); System.out.println(token.getExpire()); } ``` 测试类返回结果如下: ![图片说明](https://img-ask.csdn.net/upload/202001/22/1579675352_164301.png) 但是,业务逻辑类一直都无法正常读取内容,domain一直为null ![图片说明](https://img-ask.csdn.net/upload/202001/22/1579675405_8772.png) 请高手指点迷津。
用IDEA打包怎么能在out目录下面生成一大多小很多JAR文件?
用idea编写代码,需要分多个job执行,怎么能生成一大多小对应不同的类的jar包呢?
InteliJ IDEA中自定义YML属性中文提示乱码问题
在SpringBoot中,使用了`@ConfigurationProperties`注解自定义配置类,并引入`spring-boot-configuration-processor`jar包。在类的字段上作了注释,然后在yml中写配置时就会有提示。 ```java @Data @ConfigurationProperties(prefix = "juzi") public class MyProjectProperties { /** * 中国志愿网 */ private ChinaVolunteerProperties volunteer; } ``` 使用过程中发现注释如果是中文就会乱码,现象如图 ![](https://juzibiji-img.juzibiji.top/img/Snipaste_2019-03-27_16-57-10.png) 经过自己研究,发现原因如下: 之所以能有代码提示,是因为`spring-boot-configuration-processor`生成了一个`spring-configuration-metadata.json`文件,在`target/classes/MATE-INF`目录下。该文件编码格式为UTF-8,但是IDEA在读取此文件时使用的是GBK编码(Windows10 环境下)。所以就造成了中文乱码的问题。 ![](https://juzibiji-img.juzibiji.top/img/Snipaste_2019-03-27_16-57-19.png) 现在想到的解决办法就2个: - 将`spring-configuration-metadata.json`生成的编码格式改为GBK - 修改IDEA读取`spring-configuration-metadata.json`文件时使用的编码为UTF-8 **但是两种方法都不知道应该怎么实现,不知道有没有遇到过此问题的大佬**
Java后台生成文件,前台无法下载
在后台生成了docx文件,保存在相对路径。 然后前台点击文件列表来获取相对路径文件目录下的所有文件,以列表的形式,展示。 但是每次生成了文件无法下载,必须重启项目之后,才能下载。 直接生成,直接下载,浏览器会报找不到文件的错误,但是重启项目之后,就可以下载了。 前台代码: ``` <table class="table table-striped table-hover"> <tr> <% for (path in FilePaths){ %> <a href="/static/docx/major/${path.key}" download="${path.key}">${path.key}</a> <% } %> </tr> </table> ``` 后台代码: @Override public Map<String,String> getFileList() { Map<String,String> map = new HashMap(); String srcPath="src/main/webapp/static/docx/major"; File file = new File(srcPath); String[] files = file.list(); for (String str:files){ map.put(str,srcPath+"/"+str); } return map; }

centOS下执行.jar文件 找不到数据库的驱动类
我在idea14下写了一个java类,该类如下: public class Connectdb { public static void main(String[] args) { String driver = "com.mysql.jdbc.Driver"; String url = "jdbc:mysql://127.0.0.1:3306/test"; String user = "root"; String password = "1234"; try { Class.forName(driver); Connection conn = DriverManager.getConnection(url, user, password); System.out.println("connect"); } catch (Exception e) { e.printStackTrace(); } } } 然后利用idea,生成.jar文件,最后目录结构如下:testdb_jar文件夹下有一文件夹lib和testdb.jar文件,然后lib下放的是mysql的驱动jar包。 然后在windows下利用命令:java -jar testdb.jar 是可以执行的,连接上了数据库 但是同样的,在centOS 7下,出现如下错误: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at Connectdb.main(Connectdb.java:15) 希望大神能帮我解决下,谢谢啦!

feign MultipartFile fastdfs跨服务调用文件上传
基本情况是: 不是通过浏览器请求,是微服务中在服务启动后自动把制定目录下的文件,通过feign调用文件上传接口,将文件保存到服务器。 参考了各位的建议之后,还是报相同的错误。 贴出一段idea中的异常信息: feign.FeignException: status 500 reading RemoteFdfsService#fdfsUpload(MultipartFile); content: {"msg":"Current request is not a multipart request","code":1,"data":null} at feign.FeignException.errorStatus(FeignException.java:60) at feign.codec.ErrorDecoder$Default.decode(ErrorDecoder.java:89) at feign.SynchronousMethodHandler.executeAndDecode(SynchronousMethodHandler.java:143) at feign.SynchronousMethodHandler.invoke(SynchronousMethodHandler.java:77) at feign.hystrix.HystrixInvocationHandler$1.run(HystrixInvocationHandler.java:107) at com.netflix.hystrix.HystrixCommand$2.call(HystrixCommand.java:302) at com.netflix.hystrix.HystrixCommand$2.call(HystrixCommand.java:298) at rx.internal.operators.OnSubscribeDefer.call(OnSubscribeDefer.java:46) at rx.internal.operators.OnSubscribeDefer.call(OnSubscribeDefer.java:35) 调用部分代码(接口需要的是MultipartFile的文件参数) String filePath = "F:\\mac\\pic\\20181113184344_type[0]_ItsPlate.jpg"; File file = new File(filePath); FileInputStream fileInputStream = new FileInputStream(file); MultipartFile multipartFile = new MockMultipartFile(file.getName(), fileInputStream); String url = remoteFdfsService.fdfsUpload(multipartFile); feign: @FeignClient(value = ServiceNameConstant.FDFS_SERVICE, configuration = RemoteFdfsService.MultipartSupportConfig.class, fallbackFactory = RemoteFdfsServiceFallbackFactory.class) public interface RemoteFdfsService { /** * 上传图片并且生成缩略图 * @param file * @return */ @PostMapping(value = "/fdfs/upload_image", consumes = MediaType.MULTIPART_FORM_DATA_VALUE) String fdfsUploadImage(@RequestPart(value = "file") MultipartFile file); /** * 引用配置类MultipartSupportConfig.并且实例化 */ @Configuration class MultipartSupportConfig { @Bean public Encoder feignFormEncoder() { return new SpringFormEncoder(); } } } 烦请各路上仙指点一二,多谢。
使用SSM框架配置式开发(不用注解),为何Service中无法注入Dao?
我用Intellij Idea开发的,所以配置文件中出错会标识红色,spring-service.xml中的ref="IStudentDao"部分出错。 另外我用Maven做的项目管理,不知道是不是配置文件放置的路径有问题。附上我的项目目录结构:![图片说明](https://img-ask.csdn.net/upload/201704/17/1492434652_95958.png) 部署到Tomcat上启动后,报No adapter for handler [com.bruceliao.controller.StudentController@12bc3bf8]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler Mybatis配置文件: ``` <configuration> <!--别名--> <typeAliases> <package name="com.bruceliao.beans"/> </typeAliases> <!--Mapper的位置--> <mappers> <package name="com.bruceliao.dao"/> </mappers> </configuration> ``` Spring配置文件: spring-mybatis.xml ``` <!--注册sqlSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="configLocation" value="classpath:mybatis.xml"/> <property name="dataSource" ref="dataSource"/> </bean> <!--生成Dao代理对象--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <property name="basePackage" value="com.bruceliao.dao"/> </bean> ``` spring-service.xml ``` <!--注册Service--> <bean id="studentService" class="com.bruceliao.service.impl.StudentServiceImpl"> <property name="studentDao" ref="IStudentDao"/> </bean> ``` spring-mvc.xml ``` <bean id="/view/login.do" class="com.bruceliao.controller.StudentController"> <property name="studentService" ref="studentService"/> </bean> ``` ![图片说明](https://img-ask.csdn.net/upload/201704/17/1492435263_528738.png)
wdk8.1+vs2013中使用winusb模版开发usb设备驱动
新人一只,本身是做硬件的,现在要编写硬件(USB设备)的驱动,然后想使用winusb进行快速的驱动开发。在使用winusb之前,使用了libusb-win32下的inf工具进行inf文件的生成和安装,通过bus hound可以看到枚举,并进行的bulk in/out测试(自带的send command)。目标pc是64位的win7旗舰版。 现在状况是vs2013新建了winusb模版工程,其中drivers package中的inf文件,对其修改了VID,PID,然后进行编译生成。这时候插入usb设备(已经卸载并删除了libusb生成的驱动),更新驱动程序->选择本地的驱动文件,指向了工程的生成。但是结果是安装不成功,提示是在inf中找不到所需的段落,如图。 ![图片说明](https://img-ask.csdn.net/upload/201603/15/1458050055_333888.jpg) inf文件内容如下 ``` ; ; ksp_daq_v11_drivers.inf ; ; Installs WinUsb ; [Version] Signature = "$Windows NT$" Class = USBDevice ClassGUID = {88BAE032-5A81-49f0-BC3D-A4FF138216D6} Provider = %ManufacturerName% CatalogFile=ksp_daq_v11_drivers.cat ; ========== Manufacturer/Models sections =========== [Manufacturer] %ManufacturerName% = Standard,NT$ARCH$ [Standard.NT$ARCH$] %DeviceName% =USB_Install, USB\VID_0308&PID_0110 ; ========== Class definition =========== [ClassInstall32] AddReg = ClassInstall_AddReg [ClassInstall_AddReg] HKR,,,,%ClassName% HKR,,NoInstallClass,,1 HKR,,IconPath,%REG_MULTI_SZ%,"%systemroot%\system32\setupapi.dll,-20" HKR,,LowerLogoVersion,,5.2 ; =================== Installation =================== [USB_Install] Include=winusb.inf Needs=WINUSB.NT [USB_Install.Services] Include=winusb.inf AddService=WinUsb,0x00000002,WinUsb_ServiceInstall [WinUsb_ServiceInstall] DisplayName = %WinUsb_SvcDesc% ServiceType = 1 StartType = 3 ErrorControl = 1 ServiceBinary = %12%\WinUSB.sys [USB_Install.HW] AddReg=Dev_AddReg [Dev_AddReg] ; By default, USBDevice class uses iProduct descriptor to name the device in ; Device Manager on Windows 8 and higher. ; Uncomment for this device to use %DeviceName% on Windows 8 and higher: ;HKR,,FriendlyName,,%DeviceName% HKR,,DeviceInterfaceGUIDs,0x10000,"{fc47c010-ea60-4bed-9e8f-820bee86e7eb}" [USB_Install.CoInstallers] AddReg=CoInstallers_AddReg CopyFiles=CoInstallers_CopyFiles [CoInstallers_AddReg] HKR,,CoInstallers32,0x00010000,"WdfCoInstaller$KMDFCOINSTALLERVERSION$.dll,WdfCoInstaller" [CoInstallers_CopyFiles] WdfCoInstaller$KMDFCOINSTALLERVERSION$.dll [DestinationDirs] CoInstallers_CopyFiles=11 ; ================= Source Media Section ===================== [SourceDisksNames] 1 = %DiskName% [SourceDisksFiles] WdfCoInstaller$KMDFCOINSTALLERVERSION$.dll=1 ; =================== Strings =================== [Strings] ManufacturerName="ksp" ClassName="Universal Serial Bus devices" DiskName="ksp_daq_v11_drivers Installation Disk" WinUsb_SvcDesc="WinUSB Driver" DeviceName="ksp_daq_v11_drivers Device" REG_MULTI_SZ = 0x00010000 ``` 解决方案配置如下 ![图片说明](https://img-ask.csdn.net/upload/201603/15/1458050914_643227.jpg) 我查找了windows的log文件setupact.log(位于C:\Windows下) ``` WdfCoInstaller: [03/15/2016 20:12.05.288] DIF_INSTALLDEVICE: Pre-Processing WdfCoInstaller: [03/15/2016 20:12.05.706] error locating section [USB_Install.Wdf] in inf C:\Windows\INF\oem107.inf - status(E0000101) <no error text> WdfCoInstaller: [03/15/2016 20:12.05.849] DIF_INSTALLDEVICE: Pre-Processing WdfCoInstaller: [03/15/2016 20:12.05.937] GetDriverDetailsData: SetupDiGetSelectedDriver: status(E0000203) <no error text> WdfCoInstaller: [03/15/2016 20:12.05.993] DIF_INSTALLDEVICE: No action taken for NULL driver ``` 在出现了这个问题之后,我对比了ST-Link v2(ST公司的硬件仿真器)的inf文件(因为stlink貌似也是基于winusb开发的驱动),模版自动生成的inf文件之间的区别在于。模版的inf文件某几节中少了WinUSBCoInstaller2.dll这个文件,我向模版inf文件中添加了这些部分,但是编译不通过。报错信息如下 ``` 22.9.1: winusbcoinstaller2.dll in [coinstallers_copyfiles] of \ksp_daq_v11_drivers.inf is missing or cannot be decompressed from source media. Please verify all path values specified in SourceDisksNames, SouceDisksFiles, and CopyFiles sections resolve to the actual location of the file, and are expressed in terms relative to the location of the inf. ``` 状况描述如上,求各位给点idea

} } 上面的代码是我在网上找到的一种java操作word的方法 java读取word文档时,虽然网上介绍了很多插件poi、java2Word、jacob、itext等等,poi无法读取格式(新的API估计行好像还在处于研发阶段,不太稳定,做项目不太敢用);java2Word、jacob容易报错找不到注册,比较诡异,我曾经在不同的机器上试过,操作方法完全一致,有的机器不报错,有的报错,去他们论坛找高人解决也说不出原因,项目部署用它有点玄;itxt好像写很方便但是我查了好久资料没有见到过关于读的好办法。经过一番选择还是折中点采用rtf最好,毕竟rtf是开源格式,不需要借助任何插件,只需基本IO操作外加编码转换即可。rtf格式文件表面看来和doc没啥区别,都可以用word打开,各种格式都可以设定。 ----- 实现的功能:读取rtf模板内容(格式和文本内容),替换变化部分,形成新的rtf文档。 ----- 实现思路:模板中固定部分手动输入,变化的部分用$info$表示,只需替换$info$即可。 1、采用字节的形式读取rtf模板内容 2、将可变的内容字符串转为rtf编码 3、替换原文中的可变部分,形成新的rtf文档 这是原作者的想法,可我在使用过程中,发现替换内容中(我们参照检验药品的方法)这个中文,是不能显示的,在word里,把它转换成了iso-8859-1的编码了,不能正常显示中文,我都不知道应该在哪设置编码,才能让它正常显示,原word模板中的中文,可以正常显示,应该是在读取word模板的时候,把编码方式也读进去了,现在就是想请教一下前辈们,应该如何后,自己修改的那些中文,也可以正常显示呢 [b]问题补充:[/b] 汗,这里好象自己不能回复,所以我以这种形式回复。 先感谢一楼,二楼的回答,昨天我有事,请假没上班,所以没能及时回复,先道个歉。 先回答1楼的,在写的时候,我设置编码的话,感觉是无效的,不管我怎么设置,都没用。 再回答2楼的,特别说一下,我试了一下,发现生成的word里,那些修改部分的中文的编码形式改变了,只是还是乱码。后来我把unicode,ISO-8859-1,UTF-8,GB2312,GBK,甚至ASCII都试过了, word里都是不同形式的乱码,就是不出现汉字,真闷,我感觉是在 bs = content.getBytes("unicode"); 后,系统后来又默认的把这把转成了ISO-8859-1的形式. 可是 bs = content.getBytes("ISO-8859-1"); 我这么设置,word里的汉字是????? 真不知道为什么,要是ISO-8859-1,转ISO-8859-1,应该不会改变的哎 希望高手们,能继续解答,谢谢 [b]问题补充:[/b] 汪兆铭,您好,我不知道您一直观注这个问题,我以为要过会才能看到您的回答,所以,现在才刷新了这个页面,不好意思,先道个歉。 现在回到问题中,我照您的意思, bs = content.getBytes("unicode"); 改了一下,然后输入,可是依然不能正常显示中文,是不是,在哪,还需要再转换一次呢? [b]问题补充:[/b] mirzlm@126.com 谢谢,不知道与jdk版本或是什么的没有关系 [b]问题补充:[/b] 汪兆铭,您好,我看了一下您发的东西,我发现了问题的所在,竟然是在表格单元格里面的,就替换出来的是乱码,在表格单元格外面的,是可以正常显示的,您可以去试试,把替换的那个,放在表格里,看看,会不会成功,谢谢你的帮助 [b]问题补充:[/b] 谢谢您,给我这么多的帮助,那应该是我的那个rtf模板的问题了,真的很感谢,谢谢,谢谢,再谢谢

volatile 与 synchronize 详解
Java支持多个线程同时访问一个对象或者对象的成员变量,由于每个线程可以拥有这个变量的拷贝(虽然对象以及成员变量分配的内存是在共享内存中的,但是每个执行的线程还是可以拥有一份拷贝,这样做的目的是加速程序的执行,这是现代多核处理器的一个显著特性),所以程序在执行过程中,一个线程看到的变量并不一定是最新的。 volatile 关键字volatile可以用来修饰字段(成员变量),就是告知程序任何对该变量...
Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
