java.lang.ClassCastException: org.springframework.web.filter.CharacterEncodingFilter cannot be cast to javax.servlet.Filter at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:275)

原因：可能是包冲突了 One of your dependencies are including a servlet-api into your war file which causes that behavior. Using mvn dependency:tree, you can find out which of your dependency is that. After that you need to exclude the servlet-api as follows:

<dependency> 解决办法：

<dependency>
  <groupId>[VALUE]</groupId>
  <artifactId>[VALUE]</artifactId>
  <version>[VALUE]</version>
  <exclusions>
    <exclusion>
      <groupId>javax.servlet</groupId>
      <artifactId>servlet-api</artifactId>
    </exclusion>
  </exclusions>
</dependency>

例子：

<!-- 去除自带servlet依赖避免冲突-->
		<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
        <exclusions>
            <exclusion>
                <groupId>javax.servlet</groupId>
                <artifactId>servlet-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
