使用@ResponseBody注解返回字符串乱码

Posted 2020-08-15

方法一、在注解@RequestMapping 中添加 produces = {"application/json;charset=UTF-8"}

 方法二、在配置文件中添加：

<mvc:annotation-driven>
        <!-- 解决返回String时乱码 -->
        <mvc:message-converters register-defaults="true">
            <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>
