java - spring4 mvc rest返回中文乱码?

Question

目前是通过在每个RequestMapping注解中加入produces = {"application/json;charset=UTF-8"}来解决.但是我希望通过配置一劳永逸,在网上搜索了一下,

<mvc:annotation-driven>
    <mvc:message-converters register-defaults="true">
        <bean class="org.springframework.http.converter.StringHttpMessageConverter">
            <constructor-arg value="UTF-8" />
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

类似这种配置有很多,但是都不起作用.

Answer 1

试试把下面两个配置了

web.xml

 <!-- 编码配置 -->
  <filter>
    <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

tomcat的server.xml中加URIEncoding属性

<Connector URIEncoding="UTF-8" connectionTimeout="20000" port="80" protocol="HTTP/1.1" redirectPort="8443"/>

我是用楼主的配置起作用了。
