我正在使用REST API公开的spring-data-rest应用程序。我正在使用此API来构建Web应用程序。但我无法将此API响应转换为POJO以便于使用。我有如下如何使用RestTEmplate映射spring-data-rest JSON响应及其对象
{
"_links" : {
"self" : {
"href" : "http://localhost:8080/persons{&sort,page,size}",
"templated" : true
},
"next" : {
"href" : "http://localhost:8080/persons?page=1&size=5{&sort}",
"templated" : true
}
},
"_embedded" : {
"person": {
"id": 1,
"name": "John"
}
},
"page" : {
"size" : 5,
"totalElements" : 50,
"totalPages" : 10,
"number" : 0
}
}
restTemplate.getForObject(uri, Person.class);
这restTemplate抛出我下面的错误
22:50:10.377 [http-bio-8080-exec-28] DEBUG c.o.x.o.accessor.XWorkMethodAccessor - Error calling method through OGNL: object: [[email protected]] method: [viewPersons] args: [[]]

Person.java响应
public class Person {
private int id;
private String name;
// getters and setters
}
如何从响应Person对象?我不想在我的Persion类中包含_embedded字段。
谢谢您的回答。但我的PagedResource类型是动态的。那可能是个人或员工或访客。我不想为所有这些申报单独的课程。因为响应可能是PagedResource或资源 –
