Question

我正在使用Spring和Rstful webservices编写应用程序。

我想要格式为

的JSOn

{companies : [{name:"companyName", industry : "companyIndustry"} ,
 {name:"companyName", industry : "companyIndustry"}, ]}

但是当我触发网址时，我会以不同的格式获取JSON

{
companies: [5]
0:  {
companyName: "Uber"
industry: "Transportation"
}-
1:  {
companyName: "CVS"
industry: "Pharmacy"
}-
2:  {
companyName: "Orange"
industry: "Telecom"
}-
3:  {
companyName: "BostonDynamics"
industry: "Robotics"
}-
4:  {
companyName: "Tesla"
industry: "Transportation"
}-
-
}

我的代码

@RestController
public class CompanyController {


public static final Company companiesArray[] = {
        new Company("Uber", "Transportation"),
        new Company("CVS", "Pharmacy"), new Company("Orange", "Telecom"),
        new Company("BostonDynamics", "Robotics"),
        new Company("Tesla", "Transportation") };

@RequestMapping(value = "/companies", method = RequestMethod.GET)
private Map getAllCompanies() {
    Map companyMap = new HashMap<String,String>();
    companyMap.put("companies",  companiesArray);
    return companyMap;

}



}

其中Company对象有companyName和industry的两个String字段。

如何修改它以获得所需格式的JSON？

Answer 1

要以格式化方式返回JSON，您必须相应地创建一个视图（让我们说JsonView），如果你还没有创建任何一个。在您的XML中，您可以定义它

<bean id="jsonView" class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" >

    <property name="prefixJson" value="false" />

    <property name="objectMapper"  ref="jacksonObjectMapper" />

    <property name="renderedAttributes">

        <set>            

            <value>"Json-Value"</value>               

        </set>

    </property>     

</bean>

实际上这是我的错误，代码工作正常。因为我正在使用Chrome的Advanced Rest Client，它格式化了我的JSON结果。如果您在浏览器上调用网址，则可以正常工作。

[{"companyName":"Uber","industry":"Transportation"},{"companyName":"CVS","industry":"Pharmacy"},{"companyName":"Orange","industry":"Telecom"},{"companyName":"BostonDynamics","industry":"Robotics"},{"companyName":"Tesla","industry":"Transportation"},{"companyName":"Areva","industry":"Energy"}]

在Spring 4 RESTful Web Service中返回json数组
