SpringMVC的@ResponseBody返回字符串乱码问题解决

一、添加@RequestMapping注解，配置produces的值

@RequestMapping(value = "/add", produces = {"application/json;charset=UTF-8"})

这用方法只能修改添加了produces的@requestmapping

二、修改springmvc-xml

在springmvc-xml最前面加上下面的代码，就可以解决所有的

<!-- 转换编码为utf-8的bean, 需要放在最前面-->
    <bean
        class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
        <property name="messageConverters">
            <list>
                <bean
                    class="org.springframework.http.converter.StringHttpMessageConverter">
                    <property name="supportedMediaTypes">
                        <list>
                            <value>text/plain;charset=UTF-8</value>
                        </list>
                    </property>
                </bean>
            </list>
        </property>
    </bean>
