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>
