【Maven】发布项目到Tomcat中

初学maven，记录学习中的点滴：

将maven项目部署到tomcat实现自动化部署，参考过许多资料，也在此做个总结

开发环境

项目 版本 开发语言 Java jdk1.7 开发工具 MyEclipse10.7 中间件 Apache Tomcat 7 Maven maven 3.2.3

操作步骤

1、配置Tomcat访问权限，要打开tomcat的manager功能；在conf文件夹下的tomcat-users.xml的标签内添加如下内容

<tomcat-users>    <role rolename="admin-gui"/>    <role rolename="manager-gui"/>    <role rolename="manager-script"/>    <user username="admin" password="admin" roles="admin-gui,manager-gui"/>    <user username="deployer" password="deployer" roles="manager-script"/><tomcat-users>

2、在maven的安装路径下的settings.xml添加一个server

<server>    <id>tomcat7</id>    <username>deployer</username>    <password>deployer</password></server>

3、在项目pom.xml 的build中配置如下内容

<plugin>    <groupId>org.apache.tomcat.maven</groupId>    <artifactId>tomcat7-maven-plugin</artifactId>    <version>2.1</version>    <configuration>        <!-- 注意此处的url,修改成tomcat监听的端口即可 -->        <url>http://localhost:8080/manager/text</url>        <!-- 此处的名字必须和setting.xml中配置的ID一致-->        <server>tomcat7</server>        <username>deployer</username>        <password>deployer</password>        <!-- 此处的名字是项目发布的工程名-->        <path>/yourprj</path>        <update>true</update>    </configuration></plugin>

做完以上配置就可以进行下一步了：
在项目上右键Run As 选择Maven build，然后输入命令即可完成部署

看到如下输出则部署成功

遇到的问题

原因：Tomcat服务没有启动
解决：本地启动Tomcat即可

原因：上传大文件的时候，没有正确响应。服务器端限制的是5M
解决：修改tomcat\conf\server.xm下的Connector节点，增加maxSwallowSize=”-1”的配置；再上传大文件的时候，服务端正确响应。

<Connector maxSwallowSize="-1" connectionTimeout="20000"port="80" protocol="HTTP/1.1" redirectPort="8443"/>
