[Java知识库]解决请求中文乱码(Spring MVC)

解决请求中文乱码(Spring MVC)

1.Get请求乱码(tomcat8.0以后不需要)

在server.xml增加URIEncoding属性

URIEncoding="UTF-8"

tomcat安装目录 --> conf --> server.xml

2.Post请求乱码

在web.xml配置CharacterEncodingFilter

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

3.Response响应乱码

Spring配置StringHttpMessageConverter

applicationContext.xml 中加入下列代码

<!--启用Spring MVC的注解开发模式-->
    <mvc:annotation-driven conversion-service="conversionService">
        <!--消息转换器-->
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/plain;charset=utf-8</value>
                        <value>text/html;charset=utf-8</value>
                    </list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>
