本文详细解析了Tomcat启动过程中出现的错误，具体为：由于weixin4j中包含的javax.servlet-api与程序中已引入的同名依赖冲突，导致Tomcat启动失败。通过调整Maven坐标，排除冲突的依赖，成功解决了这一问题。

原因是在weixin4j中包含了javax.servlet-api，而程序中又引入了javax.servlet-api导致冲突

导致冲突的maven坐标

<dependency>
    <groupId>org.weixin4j.spring.boot</groupId>
    <artifactId>weixin4j-spring-boot-starter</artifactId>
    <version>1.0.0</version>
</dependency>

修改之后的maven坐标

<dependency>
    <groupId>org.weixin4j.spring.boot</groupId>
    <artifactId>weixin4j-spring-boot-starter</artifactId>
    <version>1.0.0</version>
    <!--排除旧的-->
    <exclusions>
    <exclusion>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
    </exclusion>
</exclusions>
</dependency>
