阅读本文的时候,相信你已经喜欢上了Maven优美的管理方式, 但却为构建webapp而需手动发布到Tomcat发愁,maven插件可以帮你优雅的解决这个问题。笔者最近因为项目需要,和team成员对gringotts原有项目进行改造,从ant移植到maven,本来是件很简单的事情,但因为关联到josso单点登陆,折腾了好久,现将整个过程以及遇到的一些问题做纪录,希望给碰到类似问题的同学一些参考。
1 安装josso agent
去官网下载,然后配置。请参考 http://lelglin.iteye.com/admin/blogs/1866968
2.maven tomcat插件
- Tomcat Maven plugin
- Cargo plugin
我首先试用了Tomcat Maven plugin,非常便利,但是他运行的tomcat是内嵌的,无法加载我们需要josso agent。
pom.xml文件增加配置
<build> <plugins> <!-- tomcat --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat6-maven-plugin</artifactId> <version>2.0</version> </plugin> </plugins> </build>
然后google查找maven tomcat插件运行外部tomcat的方法,网上确实也找到一下类似的问题,没有合适的解决方案,放弃。
然后我们又尝试了Cargo plugin,它是一个基于标准方式发布Web应用程序到Java EE容器的瘦包装器,它能发布到多种Web服务器,如Geronimo、Glassfish、JBoss、Tomcat、Jetty、WebLogic等。这正是我们想要的。
配置
<build> <finalName>projectName</finalName> <plugins> <plugin> <groupId>org.codehaus.cargo</groupId> <artifactId>cargo-maven2-plugin</artifactId> <configuration> <wait>true</wait> <container> <containerId>tomcat6x</containerId> <type>installed</type> <home>/Library/Tomcat</home> </container> <configuration> <type>existing</type> <home>/Library/Tomcat</home> <properties> <cargo.tomcat.manager.url>https://localhost:8080/manager</cargo.tomcat.manager.url> <cargo.remote.username>admin</cargo.remote.username> <cargo.remote.password>password</cargo.remote.password> <cargo.jvmargs>-Djava.security.auth.login.config="/Library/Tomcat/conf/jaas.conf"</cargo.jvmargs> </properties> </configuration> </configuration> <executions> <execution> <id>start-container</id> <phase>pre-integration-test</phase> <goals> <goal>deployer-deploy</goal> <!-- Only local containers can be started <goal>start</goal> --> </goals> </execution> <execution> <id>stop-container</id> <phase>post-integration-test</phase> <goals> <goal>deployer-undeploy</goal> <!-- Only local containers can be started <goal>stop</goal> --> </goals> </execution> <execution> <id>verify-deploy</id> <phase>install</phase> <goals> <goal>deployer-deploy</goal> </goals> </execution> <execution> <id>clean-undeploy</id> <phase>pre-clean</phase> <goals> <goal>deployer-undeploy</goal> <!-- Only local containers can be started <goal>stop</goal> --> </goals> </execution> </executions> </plugin> </plugins> </build> <dependencies>
问题和注意事项:
1.传递jvm参数,http://lelglin.iteye.com/admin/blogs/1866968 上的方式行不通,需要在<cargo.jvmargs>
<configuration> <type>existing</type> <home>/Library/Tomcat</home> <properties> <cargo.tomcat.manager.url>https://localhost:8080/manager</cargo.tomcat.manager.url> <cargo.remote.username>admin</cargo.remote.username> <cargo.remote.password>password</cargo.remote.password> <cargo.jvmargs>-Djava.security.auth.login.config="/Library/Tomcat/conf/jaas.conf"</cargo.jvmargs> </properties> </configuration>
2 安装josso agent的时候,会自动修改tomcat安装目录下server.xml
原本的这一行会被注释掉,改用josso自己的realm实现,这样就无法登陆tomcat manager,也就是无法通过插件部署。
<Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
josso agent修改后的配置
<Realm appName="josso" className="org.josso.tc60.agent.jaas.CatalinaJAASRealm" debug="1" roleClassNames="org.josso.gateway.identity.service.BaseRoleImpl" userClassNames="org.josso.gateway.identity.service.BaseUserImpl"/>
后来shijun同学发现 ,可以在某个context下面配置jossorealm实现,这样josso agent能够拦截到该context下的request,又不影响tomcatmanager管理应用,具体如下
<Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> <Valve appName="josso" className="org.josso.tc60.agent.SSOAgentValve" debug="1"> </Valve> <Context path="/apiConsole" docBase="/Library/Tomcat/webapps/apiConsole" debug="1" reloadable="true"> <Realm appName="josso" className="org.josso.tc60.agent.jaas.CatalinaJAASRealm" debug="1" roleClassNames="org.josso.gateway.identity.service.BaseRoleImpl" userClassNames="org.josso.gateway.identity.service.BaseUserImpl"/> </Context>
