【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

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"/>
