@RequestBody获取空值
我创建了一个简单的REST服务(POST)。但是当我从邮递员@RequestBody调用此服务时未收到任何值。
import org.springframework.http.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 org.springframework.web.servlet.ModelAndView;
@RestController
public class Add_Policy {
@ResponseBody
@RequestMapping(value = "/Add_Policy", headers = {
"content-type=application/json" }, consumes = MediaType.APPLICATION_JSON_VALUE, method = RequestMethod.POST)
public Policy GetIPCountry( @RequestBody Policy policy) {
System.out.println("Check value: " + policy.getPolicyNumber());
return policy;
}
}
我的java Bean对象如下所示:
public class Policy { private String PolicyNumber;
private String Type;
private String Tenture;
private String SDate;
private String HName;
private String Age;
public String getPolicyNumber() {
return PolicyNumber;
}
public void setPolicyNumber(String policyNumber) {
PolicyNumber = policyNumber;
}
public String getType() {
return Type;
}
public void setType(String type) {
Type = type;
}
public String getTenture() {
return Tenture;
}
System.out.println将空值打印为PolicyNumber的值。
请帮助我解决此问题。
我在请求正文中传递的JSON是
{ "PolicyNumber": "123",
"Type": "Test",
"Tenture": "10",
"SDate": "10-July-2016",
"HName": "Test User",
"Age": "10"
}
我什Content-Type
至打算application/json
去邮递员
回答:
尝试将JSON中属性的第一个字符设置为小写。例如。
{ "policyNumber": "123",
"type": "Test",
"tenture": "10",
"sDate": "10-July-2016",
"hName": "Test User",
"age": "10"
}
基本上,Spring使用getter和setter设置bean对象的属性。它采用JSON对象的属性,并将其与同名的setter匹配。例如,要设置policyNumber属性,它会尝试在您的bean类中找到一个名为setpolicyNumber()的setter,然后使用它来设置bean对象的值。
