如何更改错误无法调用 Tomcat 管理器：服务器返回 HTTP 响应代码：403

Question

运行 java-thymeleaf-maven-spring 应用程序时发生错误

这里用的是tomcat7。

这里显示步骤

1. 从 git-hub 下载项目

2. mvn clean install 显示构建成功

3. mvn tomcat:deploy 构建失败

并显示错误

[错误] 无法执行目标 org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy 项目 spring-mvc-thymeleaf 上的（默认 cli）：无法调用 Tomcat 管理器：服务器返回 HTTP 响应代码：403 用于 URL：http://localhost:8080/manager/deploy?path=%2Fspring-mvc-thymeleaf&war= -> [帮助 1]

这里下载很多程序都显示这个问题

这里显示的程序 pom.xml 文件之一

我在谷歌上搜索这个错误，但我找不到程序方面的任何问题。

tomcat 用户文件显示，

<role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>

Answer 1

您是否在 pom.xml 中包含了 maven tomcat 插件？你的 pom 的构建部分应该是这样的：

<build>
   <resources>
      <resource>
          <directory>src/main/resources</directory>
          <filtering>true</filtering>
          </resource>
   </resources>
   <plugins>
      <!-- Maven Tomcat Plugin -->
      <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>
    <configuration>
        <url>http://127.0.0.1:8080/manager</url>
        <server>TomcatServer</server>
        <path>/mkyongWebApp</path>
    </configuration>
       </plugin>
    <plugins>
</build>

您还必须为 Tomcat 添加具有管理员访问权限的用户。编辑文件——“%TOMCAT_PATH%/conf/tomcat-users.xml”并为用户tomcat添加角色管理器。

<role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager"/>
  <user username="tomcat" password="tomcat" roles="tomcat,manager"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
