get：

一.先修改tomcat配置文件

1.打开文件tomcat ---->选择conf------->选择server.xml文件打开--->大约70行左右添加utf-8

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8" />

2.检查tomcat插件在插件中添加 <uriEncoding>utf-8</uriEncoding>

<build>
    <plugins>
      <!-- 配置Tomcat插件 -->
      <plugin>
        <groupId>org.apache.tomcat.maven</groupId>
        <artifactId>tomcat7-maven-plugin</artifactId>
        <version>2.1</version>
        <configuration>
          <port>8080</port>
          <path>/</path>
           //添加这一块增加utf-8编码
          <uriEncoding>utf-8</uriEncoding>
        </configuration>
      </plugin>
    </plugins>
  </build>

3.在web.xml⽂件中配置编码为utf-8

<!-- 配置解决中⽂乱码问题。此过滤器会进⾏：request.setCharacterEncoding("utf-8") -->
<filter>
 <filter-name>encodingFilter</filter-name>
 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
 <init-param>
 <param-name>encoding</param-name>
 <param-value>utf-8</param-value>
 </init-param>
</filter>
<filter-mapping>
 <filter-name>encodingFilter</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>

4.如果用纯注解，在核心配置类重写getServletFilters

package wocd;

import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

import javax.servlet.Filter;

public class spring  extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[0];
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{config.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }

    @Override
    protected Filter[] getServletFilters() {
        CharacterEncodingFilter filter = new CharacterEncodingFilter();
        filter.setEncoding("UTF-8");
        return  new Filter[]{filter};
    }
}
