我是Spring MVC的新手,我正在公开REST服务。我的GET
服务工作正常,但Postman的POST
调用将空null
个值作为字段发送。
以下是使用各种形式的POST
注释的示例REST服务。在过去的3天里,我一直坚持这一点。请帮忙。
package com.cgi.ehr.rest;
import javax.ejb.EJB;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import com.cgi.ehr.services.dao.UserDetailsDAO;
import com.cgi.test.dto.InputDto;
@RestController
@RequestMapping("/bookmarks")
public class CheckingService {
@EJB
UserDetailsDAO userDetailsDAO;
@RequestMapping(value = "/bookmark", method = RequestMethod.GET)
public InputDto testM() {
return userDetailsDAO.testMethod();
}
@RequestMapping(value = "/testM2", method = RequestMethod.GET,headers="Accept=*/*", produces="application/json")
//@Produces(MediaType.APPLICATION_JSON)
public InputDto testM2() {
InputDto d = new InputDto("1","2");
return d;
}
@RequestMapping(value = "/bookmarkPost", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
//@ResponseBody
public InputDto testPost(InputDto inputDto) {
String age = inputDto.getTestAge();
String name = inputDto.getTestname();
InputDto dto = new InputDto();
dto.setTestAge(age + "gotback");
dto.setTestname(inputDto.getTestname() + "gotback");
return dto;
}
@RequestMapping(value = "/bookmarkPost1", method = RequestMethod.POST)
public InputDto testPost1(InputDto inputDto) {
String age = inputDto.getTestAge();
String name = inputDto.getTestname();
InputDto dto = new InputDto();
dto.setTestAge(age + "gotback");
dto.setTestname(inputDto.getTestname() + "gotback");
return dto;
}
@RequestMapping(value = "/person", method = RequestMethod.POST, headers = "Accept=application/xml, application/json")
public @ResponseBody InputDto addPerson(@RequestBody InputDto inputDto) {
return inputDto;
}
}
`
package com.cgi.test.dto;

import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class InputDto implements Serializable{

}
public InputDto() {
super();
}
public InputDto(String testname, String testAge) {
this.testname = testname;
this.testAge = testAge;
}
}

您的testPost方法应如下所示。现在您可以使用Postman使用相同的请求。
@RequestMapping(value = "/bookmarkPost", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE,consumes = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody InputDto testPost(@RequestBody InputDto inputDto) {
String age = inputDto.getTestAge();
String name = inputDto.getTestname();
InputDto dto = new InputDto();
dto.setTestAge(age + "gotback");
dto.setTestname(name + "gotback");
return dto;
}

在InputDto
班级中,您的二传手正确设置了实例变量this.testXxx
public void setTestname(String testname) {
this.testname = testname;
}
但是,您的getter不会返回此实例变量。请注意您遗失的this.
以下内容应解决您当前的问题,然后应用于两个getter。
public String getTestAge() {
return this.testAge;
}

抱歉,伙计......代码一直在运作,我在邮递员提交帖子数据时犯了一个非常愚蠢的错误(我选择了错误的标签而没有在" body"下发送)。 ..我浪费了3天!!!! ..反正再次感谢@abaghel
