解决SpringMVC使用ResponseBody返回JSON在IE浏览器出现下载文件-ie下载的文件在哪

先看一个Controller方法

@ResponseBody

@RequestMapping(value = "/getUserById/{id}",method = {RequestMethod.GET})

public User getUserById(@PathVariable int id, HttpServletRequest request, HttpServletResponse response, Model model){

response.setContentType("text/html;charset=UTF-8");

response.setHeader("content-disposition", "inline;filename=*.txt");

User user = userService.getUserById(id);

return user;

}

返回一个User实体，通过@ResponseBody注解格式化为json对象输出的页面

但是在IE浏览器下面，会出现下载json文件的提示，而不是在页面显示

解决方法1：

在controller方法中加上这个就不会出现下载，而是显示json

response.setContentType("text/html;charset=UTF-8");

response.setHeader("content-disposition", "inline;filename=*.txt");

效果如下图：

解决方法2：在spring-mvc.xml中配置

<mvc:annotation-driven>

<mvc:message-converters register-defaults="false">

<!-- 解决AJAX中文乱码 -->

<beans:bean class="org.springframework.http.converter.StringHttpMessageConverter">

<beans:constructor-arg value="UTF-8"/>

</beans:bean>

<beans:bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

<beans:property name="prettyPrint" value="false" />

<beans:property name="supportedMediaTypes">

<beans:list>

<beans:value>text/html;charset=UTF-8</beans:value>

<beans:value>application/json</beans:value>

</beans:list>

</beans:property>

<beans:property name="objectMapper">

<beans:bean class="com.fasterxml.jackson.databind.ObjectMapper">

<beans:property name="serializationInclusion">

<beans:value type="com.fasterxml.jackson.annotation.JsonInclude.Include">NON_NULL</beans:value>

</beans:property>

</beans:bean>

</beans:property>

</beans:bean>

</mvc:message-converters>

</mvc:annotation-driven>

效果如下图：

上述配置，需要依赖jar包，如果工程使用的是maven在pom.xml中加入以下依赖：

pom文件中需要下面的jar包
