java 单双引号转义字符 java中双引号转义

现象：

本来应该返回是这种：

实际上返回的双引号都被转义了 

 解决方案：

在spring文件夹下的web-home.xml中添加如下内容即可：

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter" >
        <property name="messageConverters">
            <list>
                <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
                <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>
                            <value>application/json;charset=UTF-8</value>
                        </list>
                    </property>
                </bean>
            </list>
        </property>
    </bean>




    <bean id="fastJsonHttpMessageConverter"
          class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <!--text/html在先-->
                <value>text/html;charset=UTF-8</value>
                <value>application/json;charset=UTF-8</value>
            </list>
        </property>
        <property name="fastJsonConfig">
            <bean class="com.alibaba.fastjson.support.config.FastJsonConfig">
                <property name="dateFormat" value="yyyy-MM-dd HH:mm:ss"/>
                <property name="serializerFeatures">
                    <array>
                        <!--时间格式-->
                        <value>WriteDateUseDateFormat</value>
                        <value>DisableCircularReferenceDetect</value>
                    </array>
                </property>
            </bean>
        </property>
    </bean>

希望对你有用哦~
