从Cp1252到UTF-8的Spring MVC编码请求

Question

There is a post request to my controller with JSON encoded in Cp1252 . How can I encode the request body to UTF-8 ? I use Jackson to get a POJO.

try to add this filter to your web.xml:

<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>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>



<filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

i had a similar problem and this solved it.
