Java 获取带有发送和接收json数据的pathvariable Rest spring mvc

我正在尝试使用SpringMVC学习RESTWeb服务。我跟踪了林克

我能够接收和发送Json数据，但无法通过调用传递pathvariable。我无法理解这个问题

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;
    }
}

我可以执行myAction2，但无法执行myAction1。 如果我从myAction1中删除pathvariable，一切正常

请帮忙。

我找到了解决问题的办法。有很多错误

1第一个问题是spring安全性，它正在验证url并将其重定向到登录页面

我改变了这个

<http pattern="/myRest/*" security="none" />

解决问题后

干杯

在执行GET？curl-i标志后，您将收到哪些HTTP代码，并在输出中添加HTTP头。很适合调试。我能想到的另一件事是尝试添加@PathVariableparam1字符串param1。不确定变量名是否匹配是否需要它，但我一直看到它是这样使用的。
