ant打包lombok一直编译失败,求大神指点 20C

ant打包的时候我的build.xml文件如下,只要是涉及到lombok中的内容都编译不上,例如@Slf4j的log或者lombok中的val类型,还有那些注解编译都是失败的,求大神指点

ant打包一直提示log cannot be resolved
ant打包在javac编译的时候一直提示log cannot be resolved,用的是lombok的jar包,但是打开文件log已经编译上了,造成打包一直不成功,求教大神出现 build.xml <?xml version="1.0" encoding="UTF-8"?> <!-- 定义一个工程,默认任务为warFile。 --> <project name="hera_insure_v2" default="warFile" basedir="."> <!-- 定义属性,打成war包的名称。 --> <property name="warFileName" value="hera_insure_v2.war"/> <property name="build.compiler" value="org.eclipse.jdt.core.JDTCompilerAdapter"/> <property name="ant.dir" value="D:/software/apache-ant-1.10.1/lib"/> <!-- 定义路径,编译java文件时用到的jar包。 --> <path id="project.lib"> <fileset dir="${basedir}/WebContent/WEB-INF/lib"> <include name="**/*.jar"/> </fileset> <fileset dir="${ant.dir}"> <include name="**/*.jar"/> </fileset> </path> <!-- 定义任务,清空任务:清空原有的class文件,创建新的build路径。 --> <target name="clean"> <delete dir="${basedir}/build" /> <mkdir dir="${basedir}/build" /> </target> <!--看官网这么写,自己改的--> <!-- <target name="javadoc" depends="clean"> <taskdef classname="lombok.delombok.ant.Tasks$Delombok" classpath="${basedir}/WebContent/WEB-INF/lib/lombok-1.16.6.jar" name="delombok" /> <mkdir dir="build/src-delomboked" /> <delombok verbose="true" encoding="UTF-8" to="${basedir}/build" from="${basedir}/src"> <format value="suppressWarnings:skip" /> </delombok> <javadoc sourcepath="${basedir}/src" defaultexcludes="yes" destdir="${basedir}/build" /> </target> --> <!-- 定义任务,编译src文件夹中的java文件,编译后的class文件放到创建的文件夹下。 --> <target name="compile" depends="clean"> <!--之前普通编译成功的--> <!-- <javac srcdir="${basedir}/src" destdir="${basedir}/build" includeantruntime="false" source="1.7" target="1.7"> <compilerarg line="-encoding UTF-8"/> <classpath refid="project.lib" /> </javac> --> <!--jdt编译--> <javac classpathref="project.lib" srcdir="${basedir}/src" destdir="${basedir}/build" compiler="org.eclipse.jdt.core.JDTCompilerAdapter" nowarn="false" debug="true" debuglevel="source,lines,vars" source="1.7" target="1.7" encoding="utf-8" fork="true" memoryMaximumSize="512m" includeantruntime="false"/> </target> <!--复制xml文件--> <target name="copy-xml-files" depends="compile"> <copy todir="${basedir}/build/cn/tk/hera/insure/core/"> <fileset dir="${basedir}/src/cn/tk/hera/insure/core/"/> </copy> </target> <!--复制配置文件--> <target name="copy-config-files" depends="copy-xml-files"> <copy todir="${basedir}/build/"> <fileset dir="${basedir}/resource/"/> </copy> </target> <!-- 定义默认任务,将class文件集合成jar包。 --> <target name="warFile" depends="copy-config-files"> <!-- 删除原有war包。 --> <delete dir="${basedir}/${warFileName}" /> <!-- 建立新war包。 --> <war destfile="${basedir}/${warFileName}" webxml="${basedir}/WebContent/WEB-INF/web.xml"> <!-- 将非jar和非class文件拷贝到war包的对应路径下。 --> <fileset dir="${basedir}/WebContent"> <include name="**/**.*" /> <exclude name="**/*.jar"/> <exclude name="**/*.class"/> </fileset> <!-- 将jar和class文件拷贝到war包的对应路径下。 --> <lib dir="${basedir}/WebContent/WEB-INF/lib" /> <classes dir="${basedir}/build"/> </war> </target> </project> 编译还是log不能解析 log是lombok的,所以lombok不能编译导致的
gradle 使用 apply plugin: "net.ltgt.apt-idea" 插件, 导致 lombok 失效, 这是什么原因?
// apply plugin: "net.ltgt.apt-idea" 把这个注释掉, 就可以正常运行, 是因为该apt导致lombok 的注解处理器无法使用吗? 有什么解决的办法, 谢谢

ConfigurationProperties与 lombok的注解 编译时 栈溢出
在执行 ```./gradlew assemble```时 ,出现了```java.lang.StackOverflowError```的异常。启用 ```--stacktrace```参数,发现异常栈中的方法循环调用位于这个类中```org.springframework.boot.configurationprocessor.ConfigurationMetadataAnnotationProcessor```。该类用于处理```ConfigurationProperties```注解。 如下的这个类同时打上了`@ConfigurationProperties` 和 `@Data`,移除其一 后就可以顺利编译。 是什么原因造成的呢? ```java @ConfigurationProperties(prefix = "config") @Data public class DeployGroupConfig { int a; } ``` **异常栈信息如下** ``` > java.lang.StackOverflowError * Try: Run with --info or --debug option to get more log output.

ElasticSearch 6.3.2版本整合springBoot 报错 java.io.StreamCorruptedException: invalid internal transport message format, got (48,54,54,50)
在服务器上搭建了一个单机的ElasticSearch 版本6.3.2,因为本地访问服务器的9200端口访问不到(network.host:0.0.0.0启动报错),所以用nginx做了代理9002端口对应9200,9001端口对应9300,直接访问访问成功如下:![图片说明](https://img-ask.csdn.net/upload/202002/08/1581096007_348190.jpg)![图片说明](https://img-ask.csdn.net/upload/202002/08/1581096016_248026.png)

springboot2.1.4 + jpa + hibernate 使用aop注解形式实现多数据源管理 可能懒加载出现问题求大神解答
最近项目中使用springboot2.1.4 + jpa + hibernate 使用aop注解形式实现多数据源管理,用的就是网上大多数人使用的一套代码,但是我在项目中使用后发现如果配置 spring配置文件 application.yml 中open-in-view: false 跨数据源查询正常,但是保存或者修改失败原因是事务没有提交,一旦把open-in-view改成true则不能跨数据源查询,修改保存正常事务正常提交求解,具体代码如下实现 1. application.yml ``` spring: ## 数据库配置 #datasource: #driver-class-name: com.mysql.jdbc.Driver #url: jdbc:mysql://192.168.101.125:3306/cdv?useSSL=false&characterEncoding=utf-8 #username: root #password: 123456 #url: jdbc:mysql://127.0.0.1:3306/boot-jpa-back-sys2?useSSL=false&characterEncoding=utf-8 #username: root #password: datasource: test1: driver-class-name: com.mysql.jdbc.Driver jdbc-url: jdbc:mysql://192.168.101.125:3306/cdv?useSSL=false&characterEncoding=utf-8 username: root password: 123456 type: com.alibaba.druid.pool.DruidDataSource test2: driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver jdbc-url: jdbc:sqlserver://192.168.101.125:1433;database=Test;

lombok和swagger的冲突
# 在实体类上使用@Data注释会导致Swagger的@ApiResponse内容显示不出来 # ## 实体类说明 ![图片说明](https://img-ask.csdn.net/upload/201910/28/1572254883_117534.png) ## swagger ![图片说明](https://img-ask.csdn.net/upload/201910/28/1572254941_672128.png) ## 显示结果 ![图片说明](https://img-ask.csdn.net/upload/201910/28/1572254490_627125.png) 但是如果将@Data注解去掉改成getter()和setter(),数据又能够出来了
eclipse 使用 lombok get set方法报错
配置了 lombok 在代码中使用注解也有提示 但是get set方法一直报错 不知道怎么回事 ,求解答

自己定义了一个注解:@AttributeJudge 想用在实体类的属性上面。 ``` @Target({ElementType.METHOD, ElementType.FIELD}) @Retention(RetentionPolicy.RUNTIME) @Documented @Inherited // 允许继承 public @interface AttributeJudge ``` 实体类: ``` @Data @Entity @Table(name = "XXXX") public class UserInfo implements Serializable { /** * 用户Id */ @Id private String userId; /** * 用户名称 */ @AttributeJudge private String userName; } ``` 在控制层(controller都能切入),但是在实体类属性上面无法切入。 ``` @Aspect @Component public class AttributeJudgeAsprct { // 配置织入点 @Pointcut("@annotation(com.cocosum.blog.core.AttributeJudge.AttributeJudge)") public void attributePointCut() { } @Around("attributePointCut()") public Object around(ProceedingJoinPoint pjp) throws Throwable { System.out.println(pjp); // 获取注解的 方法参数列表 Object[] args = pjp.getArgs(); System.out.println(args); // 放行 return pjp.proceed(); } } ``` 求解,大佬们!!!!! 其实我想的是判断数据为空,如下: ``` if (StringUtils.isBlank(userName)) { return ResultUtils.returnError("用户名不能为空"); } if (StringUtils.isBlank(userPassword) || userPassword.length() < 6) { return ResultUtils.returnError("密码长度不能小于6位"); } ``` 每次都写这种,很无奈,我想直接加一个注解,在实体类的属性上: 比如我的注解: @AttributeJudge(isNull = YES, title = "用户名不能为空") private String userName; 然后我去捕获。后台统一返回一个json。 有没有好的建议.......

vue前端websocket连接不上springboot,报错Connection closed before receiving a handshake response
搞定了,我的代码写的基本没有问题,毕竟都是按着教程一步一步来的,主要问题在于,我的开发环境和教程不一致,我是前后端分离,请求8080即请求的前端项目,当然会超时然后建立连接失败。我查看了一下前后端各自的端口:前端8080,后端63000,然后把 ``` this.sock = new WebSocket("ws:localhost:8080/websocket");//建立连接 ``` 改成 ``` this.sock = new WebSocket("ws:localhost:63000/websocket");//建立连接 ``` 就可以了,换成后端的端口号。 --- 以下是原问题 --- 照着网上的教程写的例子,整合到自己的项目中。前端用vue写的,js里几乎和教程一模一样,主要问题在于 ``` this.sock = new WebSocket("ws:localhost:8080/websocket");//建立连接 ``` --- **创建的websocket内的方法都是null,如图:** ![图片说明](https://img-ask.csdn.net/upload/201909/24/1569293600_266157.png) --- **然后观察控制台内过了一段时间报错,提示:** ``` WebSocket connection to 'ws://localhost:8080/websocket' failed: Connection closed before receiving a handshake response ``` --- **控制台错误详情见图:** ![图片说明](https://img-ask.csdn.net/upload/201909/24/1569294057_247788.png) --- **前端代码:** ``` webSocket() { debugger; // 建立socket连接 if ('WebSocket' in window) {//判断当前浏览器是否支持webSocket // this.sock = new WebSocket("ws:localhost:8080/bootTest/websocket");//建立连接(带后端项目名) this.sock = new WebSocket("ws:localhost:8080/websocket");//建立连接(不带后端项目名) } else { alert('你的浏览器暂不支持websocket :('); } var sock = this.sock; console.log(sock); sock.onopen = function (e) {//成功建立连接 console.log(e); }; sock.onmessage = function (e) {//接收到消息 console.log(e) $(".message").append("<p><font color='red'>"+e.data+"</font>") }; sock.onerror = function (e) {//连接发生错误 console.log(e); }; sock.onclose = function (e) {//连接关闭 console.log(e); }; ////监听窗口关闭事件,当窗口关闭时,主动去关闭websocket连接,防止连接还没断开就关闭窗口,server端会抛异常。 window.onbeforeunload = function(){ websocket.close(); }; } ``` --- --- --- --- 后端代码: ``` import java.io.IOException; import java.util.concurrent.CopyOnWriteArraySet; import javax.websocket.server.PathParam; import javax.websocket.server.ServerEndpoint; import javax.websocket.*; import lombok.extern.slf4j.Slf4j; @Slf4j @ServerEndpoint("/websocket") public class WebSocketServer { //静态变量,用来记录当前在线连接数。应该把它设计成线程安全的。 private static int onlineCount = 0; //concurrent包的线程安全Set,用来存放每个客户端对应的MyWebSocket对象。 private static CopyOnWriteArraySet<WebSocketServer> webSocketSet = new CopyOnWriteArraySet<WebSocketServer>(); //与某个客户端的连接会话,需要通过它来给客户端发送数据 private Session session; /** * 连接建立成功调用的方法*/ @OnOpen public void onOpen(Session session) { this.session = session; webSocketSet.add(this); //加入set中 addOnlineCount(); //在线数加1 log.info("有新连接加入!当前在线人数为" + getOnlineCount()); try { sendMessage("连接成功"); } catch (IOException e) { log.error("websocket IO异常"); } } // //连接打开时执行 // @OnOpen // public void onOpen(@PathParam("user") String user, Session session) { // currentUser = user; // System.out.println("Connected ...

Springboot整合Shiro 记住密码(RememberM)之后怎么实现重启浏览器,我的登录信息也不过期?
1. cookie管理对象 ``` @Bean public CookieRememberMeManager cookieRememberMeManager() { CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager(); SimpleCookie simpleCookie = new SimpleCookie("rememberMe"); simpleCookie.setMaxAge(259200000); cookieRememberMeManager.setCookie(simpleCookie); cookieRememberMeManager.setCipherKey(Base64.decode("6Zm+6I2j5Y+R5aS+5ZOlAA==")); return cookieRememberMeManager; } ``` 2. 上面可以实现cookie保存,重启浏览器,无需登录;但是我发现,cookie虽在, 如我重启之后,ajax调用getRequest().getSession().getAttribute("userName") 这个时候发现Session已经不存在。会报java.lang.NullPointerException空指针异常。在网上找了博客,有些有人说关闭浏览器cookie都也释放了,但是我上面确实也能实现关闭重启之后无需登录,只要不获取session。在程序里面不获取session不可能的。 * 哪位大佬能给点解释?怎么才能实现关闭浏览器session也不过期? 记住密码之后,关闭浏览器,重启电脑再次打开也无需登录? ## **解决办法:** ``` /** * cookie对象; * @return */ @Bean public SimpleCookie rememberMeCookie(){ // 这个参数是cookie的名称,对应前端的checkbox的name = rememberMe SimpleCookie simpleCookie = new SimpleCookie("rememberMe"); // cookie生效时间30天,单位秒; simpleCookie.setMaxAge(2592000); // 浏览器中通过document.cookie可以获取cookie属性,设置了HttpOnly=true,在脚本中就不能的到cookie,可以避免cookie被盗用 simpleCookie.setHttpOnly(true); // JSESSIONID的path为/用于多个系统共享JSESSIONID simpleCookie.setPath("/"); return simpleCookie; } /** * cookie管理对象;记住我功能 * @return */ @Bean public CookieRememberMeManager rememberMeManager(){ CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager(); cookieRememberMeManager.setCookie(rememberMeCookie()); // rememberMe cookie加密的密钥 建议每个项目都不一样 默认AES算法 密钥长度(128 256 512 位) cookieRememberMeManager.setCipherKey(Base64.decode("2A2V+RFLUs+eTA3Kpr+dag==")); return cookieRememberMeManager; } /** * 自定义过滤器 * @author : fyk * @create : 2019/11/14 16:12 **/ @Bean public CustomUserFilter customUserFilter() { CustomUserFilter customUserFilter = new CustomUserFilter(); return customUserFilter; } ``` ``` package com.cocosum.blog.core.shiro.filter; import com.cocosum.blog.commons.utils.SysConstant; import com.cocosum.blog.system.entity.UserInfo; import lombok.extern.slf4j.Slf4j; import org.apache.shiro.subject.Subject; import org.apache.shiro.web.filter.AccessControlFilter; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpSession; import java.util.Objects; /** * 自定义过滤器 * @author : fyk * @create : 2019/11/14 17:06 **/ @Slf4j public class CustomUserFilter extends AccessControlFilter { @Override protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception { Subject subject = getSubject(request, response); if (subject == null) { return false; } // 转成HttpSession对象 HttpSession session = ((HttpServletRequest) request).getSession(); // 获取当前登录用户(获取用户) Object userName = session.getAttribute(SysConstant.UserConstant.USER_NAME); // 如果因为session过时或者浏览器关闭,导致保存的登录信息随着session的关闭而清空了 if (Objects.isNull(userName)) { // 获取主体信息, session被清空之后,主体信息不会被清除掉 UserInfo userInfo = (UserInfo) subject.getPrincipal(); if (Objects.nonNull(userInfo)) { session.setAttribute(SysConstant.UserConstant.USER_NAME, userInfo.getUserName()); } else { // 否则session与主体信息都为空,那就说明没有登录。则需要重新登录 } } return true; } @Override protected boolean isAccessAllowed(ServletRequest servletRequest, ServletResponse servletResponse, Object o) throws Exception { return true; } @Override protected boolean onAccessDenied(ServletRequest servletRequest, ServletResponse servletResponse) throws Exception { return true; } } ```

Python实战:抓肺炎疫情实时数据,画2019-nCoV疫情地图
文章目录1. 前言2. 数据下载3. 数据处理4. 数据可视化 1. 前言 今天,群里白垩老师问如何用python画武汉肺炎疫情地图。白垩老师是研究海洋生态与地球生物的学者,国家重点实验室成员,于不惑之年学习python,实为我等学习楷模。先前我并没有关注武汉肺炎的具体数据,也没有画过类似的数据分布图。于是就拿了两个小时,专门研究了一下,遂成此文。 2月6日追记:本文发布后,腾讯的数据源多次变更u
智力题(程序员面试经典)
NO.1  有20瓶药丸,其中19瓶装有1克/粒的药丸,余下一瓶装有1.1克/粒的药丸。给你一台称重精准的天平,怎么找出比较重的那瓶药丸?天平只能用一次。 解法 有时候,严格的限制条件有可能反倒是解题的线索。在这个问题中,限制条件是天平只能用一次。 因为天平只能用一次,我们也得以知道一个有趣的事实:一次必须同时称很多药丸,其实更准确地说,是必须从19瓶拿出药丸进行称重。否则,如果跳过两瓶或更多瓶药
在家远程办公效率低?那你一定要收好这个「在家办公」神器!
相信大家都已经收到国务院延长春节假期的消息,接下来,在家远程办公可能将会持续一段时间。 但是问题来了。远程办公不是人在电脑前就当坐班了,相反,对于沟通效率,文件协作,以及信息安全都有着极高的要求。有着非常多的挑战,比如: 1在异地互相不见面的会议上,如何提高沟通效率? 2文件之间的来往反馈如何做到及时性?如何保证信息安全? 3如何规划安排每天工作,以及如何进行成果验收? ......
作为一个程序员,内存和磁盘的这些事情,你不得不知道啊!!!
截止目前,我已经分享了如下几篇文章: 一个程序在计算机中是如何运行的?超级干货!!! 作为一个程序员,CPU的这些硬核知识你必须会! 作为一个程序员,内存的这些硬核知识你必须懂! 这些知识可以说是我们之前都不太重视的基础知识,可能大家在上大学的时候都学习过了,但是嘞,当时由于老师讲解的没那么有趣,又加上这些知识本身就比较枯燥,所以嘞,大家当初几乎等于没学。 再说啦,学习这些,也看不出来有什么用啊!
2020年的1月,我辞掉了我的第一份工作
其实,这篇文章,我应该早点写的,毕竟现在已经2月份了。不过一些其它原因,或者是我的惰性、还有一些迷茫的念头,让自己迟迟没有试着写一点东西,记录下,或者说是总结下自己前3年的工作上的经历、学习的过程。 我自己知道的,在写自己的博客方面,我的文笔很一般,非技术类的文章不想去写;另外我又是一个还比较热衷于技术的人,而平常复杂一点的东西,如果想写文章写的清楚点,是需要足够...
别低估自己的直觉,也别高估自己的智商
所有群全部吵翻天,朋友圈全部沦陷,公众号疯狂转发。这两周没怎么发原创,只发新闻,可能有人注意到了。我不是懒,是文章写了却没发,因为大家的关注力始终在这次的疫情上面,发了也没人看。当然,我...
Java坑人面试题系列: 包装类(中级难度)
Java Magazine上面有一个专门坑人的面试题系列: https://blogs.oracle.com/javamagazine/quiz-2。 这些问题的设计宗旨,主要是测试面试者对Java语言的了解程度,而不是为了用弯弯绕绕的手段把面试者搞蒙。 如果你看过往期的问题,就会发现每一个都不简单。 这些试题模拟了认证考试中的一些难题。 而 “中级(intermediate)” 和 “高级(ad
Spring Boot 2.x基础教程:使用JdbcTemplate访问MySQL数据库
在第2章节中,我们介绍了如何通过Spring Boot来实现HTTP接口,以及围绕HTTP接口相关的单元测试、文档生成等实用技能。但是,这些内容还不足以帮助我们构建一个动态应用的服务端程序。不论我们是要做App、小程序、还是传统的Web站点,对于用户的信息、相关业务的内容,通常都需要对其进行存储,而不是像第2章节中那样,把用户信息存储在内存中(重启就丢了!)。 对于信息的存储,现在已经有非常非常多...
