I am able to receive and send Json data but I am not able to pass pathvariable with the call. 我能够接收和发送Json数据,但无法在调用中传递pathvariable。 I am unable to understand the issue.
我无法理解该问题。
Here is my controller: 这是我的控制器:
package com.akash.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
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;
@Controller
@RequestMapping(value = "/myRest")
public class MyRestController {
@RequestMapping(value = "/myAction1/{param1}/", method = RequestMethod.GET, headers = "Accept=application/json")
public @ResponseBody List<Abc> myAction1(@PathVariable String param1) {
Abc ob = new Abc();
ob.setAge(20);
ob.setName("obama-"+param1);
List<Abc> listOfAbc = new ArrayList<Abc>();
listOfAbc.add(ob);
return listOfAbc;
}
/*
* curl -X GET -H "Accept:application/json"
* http://localhost:8080/myRest/myAction1/123
*/
@RequestMapping(value = "/myAction2", method = RequestMethod.POST, headers = {
"Accept=application/json", "Content-type=application/json" })
public @ResponseBody List<Abc> myAction2(@RequestBody AbcWrapper wrapper) {
Abc ob = new Abc();
ob.setAge(wrapper.getListOfAbc().size());
ob.setName("obama");
List<Abc> listOfAbc = new ArrayList<Abc>();
listOfAbc.add(ob);
return listOfAbc;
}
/*
* curl -X POST -H "Accept: application/json" -H
* "Content-Type: application/json" http://localhost:8080/myRest/myAction2
* -d "{\"listOfAbc\":[{\"age\":20,\"name\":\"akash\"}]}"
*/
}
class Abc {
private int age;
private String name;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
class AbcWrapper {
List<Abc> listOfAbc;
public List<Abc> getListOfAbc() {
return listOfAbc;
}
public void setListOfAbc(List<Abc> listOfAbc) {
this.listOfAbc = listOfAbc;
}
}
I am able to execute myAction2 but myAction1 cannot be executed. 我可以执行myAction2,但无法执行myAction1。 If I remove pathvariable from myAction1 everything works fine.
如果我从myAction1中删除pathvariable,一切正常。
Please help. 请帮忙。
I found the solution to my problem. 我找到了解决我问题的方法。 There were many mistakes.
有很多错误。
(1)The first problem was spring security which was authenticating the url and redirecting it to login page. (1)第一个问题是spring安全性,它对URL进行身份验证并将其重定向到登录页面。
I changed this 我改变了这个
<http pattern="/myRest/*" security="none" />
to 至
<http pattern="/myRest/**" security="none" />
(2)Changed myAction1 method to (2)将myAction1方法更改为
@RequestMapping(value = "/myAction1/{param1}", method = RequestMethod.GET, headers = "Accept=application/json")
public @ResponseBody List<Abc> myAction1(@PathVariable("param1") String param1, Model model) {
removed an extra slash after {param1} 在{param1}之后删除了一个额外的斜杠
All that information I got from curl -i parameter 我从curl -i参数获得的所有信息
