Maven入门示例(4):自动部署Tomcat错误排除

在Maven与Tomcat配合部署过程中,最常见的错误有三种,折腾了半天,终于找到三种错误产生的原因,以及相应的完美解决办法

1.Connection refused错误

报错信息如下:

[ERROR]Failed to execute goal org.apache.tomcat.maven: tomcat7-maven-plugin: 2.0- SNAPSHOT: deploy (default-cli) on project helloworld: Cannot invoke Tomcat manager: Connection refused: connect -> [Help 1]

原因:未启动Tomcat服务器

解决办法:先启动Tomcat服务器再选择Run

2. 401错误

报错信息如下:

[ERROR] Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin: 2.0-SNAPSHOT:deploy (default-cli) on project helloworld: Cannot invoke Tomcat manager: Server returned HTTP response code: 401 for URL: http://localhost:8080/manager/text/deploy?path=%2Fhelloworld -> [Help 1]

原因:权限问题

解决办法在$CATALINA_BASE/conf/tomcat-users.xml,

如D:\apache-tomcat-7.0.34\conf\tomcat-users.xml文件中添加权限

<role rolename=”manager”/>

<user username=”admin” password=”admin” roles=”manager”/>

修改pom.xml文件,在<configuration>  </configuration>中添加

<username>admin</username>  <password>admin</password>

3.403错误

报错信息如下:

[ERROR] Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin: 2.0-SNAPSHOT:deploy (default-cli) on project helloworld: Cannot invoke Tomcat manager: Server returned HTTP response code: 403 for URL: http://localhost:8080/manager/html/deploy?path=%2Fhelloworld -> [Help 1]

原因:产生该问题有可能因为两个原因,具体参见解决办法

解决办法:

1)如果使用的是Tomcat 7,需要修改pom.xml中部署的url地址,将<url>http://localhost:8080/manager</url>改<url>http://localhost:8080/manager/text</url>

2)给tomcat用户权限分配上,需要同时具备manager-gui和manager-script权限,我在遇到该问题时,就是忘了分配manager-script权限。

正确的conf/tomcat-users.xml配置应为:

<tomcat-users>

<role rolename="manager-gui"/>

<role rolename="manager-script"/>

<user username="admin” password="admin" roles="manager-gui, manager-script"/>

</tomcat-users>
