最新SpringMVC 4，如何解决@ResponseBody时，String类型乱码

Answer 1

web.xml里头添加如下代码，改成你使用的编码

<filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter
    </filter-class>
    <init-param>
        <!-- 等价于ServletRequest.setCharacterEncoding(java.lang.String) -->
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <!-- 追加设置ServletResponse的编码格式同ServletRequest的编码格式一致
            即response.setCharacterEncoding(“XXXX”),认值为false -->
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
