多环境下eclipse如何配置tomcat加载指定properties文件

项目背景:maven项目,有多个环境:dev、sit、uat、pat。之前用的Idea和jetty,现在因项目需要切换成了eclipse和tomcat。
问题描述:maven打的是sit的包,war包放到tomcat下单独运行没有问题,但是用eclipse内置的tomcat启动就会报错,我看了项目根目录下.metadata.plugins\org.eclipse.wst.server.core\里的webapps项目文件,发现每次启动服务加载的都是dev.properties文件,但是之前maven打的war包里面是sit.properties文件呀,tomcat怎么又重置成dev了呢?eclipse里该怎么配置tomcat让它跟随环境加载.properties文件呢?有木有大神和我遇到的是同一个问题?

7个回答

这了可以用maven的打包命令实现,再加上pom文件的配置

可以使用maven管理项目,在pom.xml文件中配置

首先你要准备多个tomcat,随意你配置多少个。操作方式是:右键项目名称-->Properties-->找到Targeted Runtimes 里面就显示的是你配置的tomcat了。你如果想要让tomcat同时在eclipse上运行的话,你需要配置不同的端口号。

多谢各位大神的回复,问题解决了,辛酸路程如下,真是一步一个坑:

1、先在项目pom文件中添加插件tomcat-maven-plugin,配置如下:

org.apache.tomcat.maven
tomcat7-maven-plugin
2.2

/helloworld
8888
UTF-8


2、maven运行tomcat命令:tomcat:run,profiles选择sit,本来以为这次就好了,结果又报错:
严重:Exception starting filter encodingFilter
java.lang.ClassCastException:org.springframework.web.filter.CharacterEncodingFilter cannot be cast to javax.servlet.Filter
解决办法:
tomcat-maven-plugin中的jar包与项目pom文件里的jar包冲突了,pom文件找到servlet-api,添加scope,配置如下:

javax.servlet
servlet-api
2.5
provided

3、再次启动服务,心想这次应该OK了吧,结果尼玛又报错:找不到jndi数据源
解决办法:
在项目/target/tomcat/conf目录下添加配置好数据源的context.xml和server.xml文件
4、再次启动服务,这次应该没报错了吧,结果又一次失望了,又报warning了:
[INFO] Downloading: https://repo.maven.apache.org/maven2/org/codehaus/mojo/tomcat-maven-plugin/maven-metadata.xml
[WARNING] Could not transfer metadata org.codehaus.mojo:tomcat-maven-plugin/maven-metadata.xml from/to central (https://repo.maven.apache.org/maven2)

tomcat启动到这里,就停在这里不动了。。。。。

解决办法:把maven命令tomcat:run改为tomcat7:run。再运行就好,tomcat7还真是奇葩。。。。。。

咦,为什么step1和step3中的pom配置代码段格式给我转换没了呢,再发一次试试:

 1、项目pom文件中添加插件tomcat-maven-plugin,配置如下:
       <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <path>/helloworld</path>
                    <port>8888</port>
                    <uriEncoding>UTF-8</uriEncoding>
                </configuration>
            </plugin>
 3、pom文件找到servlet-api,添加scope,配置如下:
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
        <scope>provided</scope>
    </dependency>

tomcat需要配置什么才能加载class

开发工具:eclipse3.4+tomcat6.0 我用我们公司平台做开发,本来一直都是用websphere的,由于准备給朋友做一个进销存的小系统,如果到时候給朋友电脑上装个websphere那显然不太可能,太耗内存...所以选择用tomcat...我把平台解压出来放到eclipse里,把tomcat配置好,然后运行tomcat,可以访问,没有问题..后来我在src目录下写自己的类.在运行的时候在加载xml的时候说找不到相应的类,我想是class没加载到tomcat下面, 我tomcat下conf/server.xml里面是这样配置的.工程在我D盘的demo下..是不是还需要更改什么配置文件才能自动加载class? <Context path="/product" reloadable="true" docBase="D:\demo\products" workDir="D:\demo\products\work" /> [b]问题补充:[/b] 晕,肯定是src下面的类都编译成功,生成了class文件 [b]问题补充:[/b] 绝对正确..加个QQ聊几句?这问题困恼我一天了.我QQ3732246 [b]问题补充:[/b] 我公司用的平台是编译好以后就直接生成到跟WEB-INF评级的bin目录下,这有区别吗?一定要放到class下??

Sring mvc +mybatis部署tomcat导致tomcat启动假死

mybatis如果出现如下错误![图片说明](https://img-ask.csdn.net/upload/201506/01/1433123778_266118.png)会导致tomcat假死并且等待很长时间才报错,错误信息不准确,导致tomcat栈溢出,修改了tomcat内存参数之后,错误原因可以看出来,但是tomcat终端一直报错,停不下来,求解 <description>Spring公共配置 </description> <!-- 使用annotation 自动注册bean, 并保证@Required、@Autowired的属性被注入 --> <context:component-scan base-package="com.hukan.hkhx"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> <context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice" /> </context:component-scan> <!-- MyBatis配置 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 --> <property name="typeAliasesPackage" value="com.hukan.hkhx.entity" /> <!-- 显式指定Mapper文件位置 --> <property name="mapperLocations" value="classpath:/mybatis/*/*Mapper.xml" /> </bean> <!-- 扫描basePackage下所有以@MyBatisRepository标识的 接口 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.hukan.hkhx.repository.*" /> <property name="annotationClass" value="com.base.common.MyBatisRepository" /> </bean> <!-- 另一个事务管理器, Jdbc单数据源事务 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 使用annotation定义事务 --> <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" /> <!-- JSR303 Validator定义 --> <!-- <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" /> --> <!-- production环境 --> <beans profile="production"> <context:property-placeholder ignore-unresolvable="true" location="classpath*:/application.properties" /> <!-- 数据源配置, 使用Tomcat JDBC连接池 --> <bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close"> <!-- Connection Info --> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- Connection Pooling Info --> <property name="maxActive" value="${jdbc.pool.maxActive}" /> <property name="maxIdle" value="${jdbc.pool.maxIdle}" /> <property name="minIdle" value="0" /> <property name="defaultAutoCommit" value="false" /> </bean>

Maven + SpringBoot开发时,多模块下配置文件如何配置问题

项目结构如下: ![图片说明](https://img-ask.csdn.net/upload/201803/17/1521255069_342527.png) 如上图,项目中有两个web工程,需要分别启动,applicaion.properties中只有Tomcat和port和webroot不一样,我在网上搜了大部分都是在说多环境配置,这种方式我会用没有问题。 当我把application-basic.properties文件放在common的resources下时,子工程中的application.properties中写下:spring.profiles.active=basic,项目编译后完全没有引入,意料之中,在此请都一些有过类似问题或者是知道好方法的朋友,给指点一下,感激不尽。。。

关于java打包后,读取不到配置文件的问题

最近做了一个项目,打包后读取不到配置文件,在eclipse中运行正常。 目录结构如下: |——ChangeLanguage |——ResourceManager |——i18n |——message_en_US.properties |——message_zh_CN.properties 下面是主要代码: [code="java"] private static final String RESOURCE_NAME = "i18n.Message"; private ResourceBundle bundle; private Locale locale; locale = new Locale("zh", "CN"); bundle = ResourceBundle.getBundle(RESOURCE_NAME, locale); [/code] 请问怎么才能读取到配置文件? 说明一下,我用 java -jar xx.jar运行时也能读取到配置文件;但是,当我用 @start javaw xxpackage.xxmain 运行时 就读取不到配置文件了。我也把i18n所在的jar加入到classpath中去了。

Spring-boot项目中,application.properties中自定义地址无法识别

在application.properties中添加了自定义地址,反复检查过地址中有该文件,但是项目运行后,还是报错,显示“没有那个文件或目录,而且为什么application.property文件中,有属性显示无法识别,这个要怎么调整?初涉web项目,希望大牛们能帮我看看这个问题,先谢谢大家了!如果还需要补充文件的,请大家和我说哈! ![图片说明](https://img-ask.csdn.net/upload/201903/05/1551750668_950835.png) ![图片说明](https://img-ask.csdn.net/upload/201903/04/1551668912_969913.png)

web项目中获取配置文件路径问题

现在做的是maven搭建的spring mvc项目,在service层获取code.properties![图片说明](https://img-ask.csdn.net/upload/201609/20/1474364759_754966.png) 代码如下 ``` public static void updateProperties(String fileName,Map<String, String> keyValueMap) { //String filePath = CodeTools.class.getClass().getResource("/").getPath(); String filePath = Thread.currentThread().getContextClassLoader().getResource(fileName).getPath(); // String filePath = ClassLoader.getSystemClassLoader().getResource(fileName).getPath(); Properties props = null; BufferedWriter bw = null; try { filePath = URLDecoder.decode(filePath,"utf-8"); props = PropertiesLoaderUtils.loadProperties(new ClassPathResource(fileName)); // 写入属性文件 bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filePath))); props.clear();// 清空旧的文件 for (String key : keyValueMap.keySet()) props.setProperty(key, keyValueMap.get(key)); props.store(bw, ""); } catch (IOException e) { } finally { try { bw.close(); } catch (IOException e) { e.printStackTrace(); } } } ``` 这个类在service层里,这里获取的filePath路径 转码后如下: file:/D:/work space/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/ctoc-manage/WEB-INF/lib/ctoc-service-0.0.1-SNAPSHOT.jar!/code.properties 这个路径 在这行就找不到了 bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filePath))); 单独测试的时候是没有问题的,路径没这么复杂。在项目里就不知道 这是什么路径,求解!!! 我换了个tomcat地址,路径为: file:/D:/apache-tomcat-7.0.68/wtpwebapps/ctoc-seller/WEB-INF/lib/ctoc-service-0.0.1-SNAPSHOT.jar!/code.properties ctoc-service被打了包,ctoc-service-0.0.1-SNAPSHOT.jar! ,在tomcat里面怎么获取这个类的地址? 带架包的路径 输出流都不能生成。 被这些路径搞得头都晕了,help!

CLASSPATH中的jar包

有个问题,就是MyEclipse中新建一个Java Project或者Web Project,然后如何获取它的CLASSPATH下的所有jar包的名字? ps: 问题标签的分类不对啊~! [b]问题补充:[/b] 有个问题,就是MyEclipse中新建一个Java Project或者Web Project,然后如何获取它的CLASSPATH下的所有jar包的名字? ps: 问题标签的分类不对啊~! [quote] 你可以用System.getProperty得到环境变量的值,然后用java.io.File找到里面所有的文件。 [/quote] 这个可以的. [quote] 工程的classpath全部在工程根目录下的.classpath文件中呢,点号开头,可以通过分析这个入手,另外,这个文件中有些classpath配置项目是引用的eclipse环境变量,eclipse环境变量可以通过JDT提供的API获取真实的所有jar包 [/quote] 这个办法无法获取web容器中的classpath中的jar包 Properties p = System.getProperties(); Set<?> s = p.keySet(); for (Iterator<?> iterator = s.iterator(); iterator.hasNext();) { String key = (String) iterator.next(); String value = p.getProperty(key); if(key.equals("java.class.path")){ String[] jar = value.split(";"); for (int i = 0; i < jar.length; i++) { System.out.println(jar[i]); } } }

玩转springboot启动banner定义所得

最近接手了一个springboot项目,不是不熟悉这个框架,启动时打印的信息吸引了我。 这不是我熟悉的常用springboot的打印信息啊,我打开自己的项目: 还真是的,不用默认的感觉也挺高大上的。一时兴起,就去研究了一下源代码,还正是有些收获,稍后我会总结一下。正常情况下做为一个老程序员,是不会对这种小儿科感兴趣的,不就是一个控制台打印嘛。哈哈! 于是出于最初的好奇,研究了项目的源代码。看到

有小伙伴问松哥这个问题,他在上海某公司,在离职了几个月后,前公司的领导联系到他,希望他能够返聘回去,他很纠结要不要回去? 俗话说好马不吃回头草,但是这个小伙伴既然感到纠结了,我觉得至少说明了两个问题:1.曾经的公司还不错;2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说,松哥之前也有过类似的经历,今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点,就是离职了也没必要和老东家弄的苦...

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...
