基于Spring Boot的web 项目,客户端浏览器分别用get、put、post访问该web服务资源

先创建一个springboot项目：

点击next

输入项目信息（注意将java version改为8）

选择web->spring web然后点击next

选择路径，然后finish

 

项目结构如上，接下来进行编码

 Count:

package com.me.redis.resouce.bean;

public class Count {
    private int count;

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }
}

 ResourceController:

package com.me.redis.resouce.controller;

import com.me.redis.resouce.bean.Count;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import com.me.redis.resouce.service.ResourceService;

@RestController
public class ResourceController {

    @Autowired
    ResourceService resourceService;

    @RequestMapping(value = "/me/count", method = RequestMethod.PUT)
    @ResponseBody
    public void initCount(@RequestBody Count count){
        resourceService.initCount(count);
    }

    @RequestMapping(value = "/me/count", method = RequestMethod.POST)
    @ResponseBody
    public void modifyCount(@RequestBody Count count){
        resourceService.addCount(count);
    }

    @RequestMapping(value = "/me/count", method = RequestMethod.GET)
    @ResponseBody
    public  Count getCount()
    {
        return resourceService.getCount();
    }
}

 ResourceManager:

package com.me.redis.resouce.manager;

public class ResourceManager {
    private int count = 0;

    private static ResourceManager instance = new ResourceManager();

    private ResourceManager(){}

    public static ResourceManager getInstance(){
        return instance;
    }

    public synchronized void addCount(int i){
        count = count + i;
    }

    public synchronized  void minusCount(int i){
        count = count -i;
    }

    public int getCount(){
        return count;
    }

    public void initCount(int i){
        count = i;
    }
}

ResouceService:

package com.me.redis.resouce.service;

import com.me.redis.resouce.bean.Count;
import com.me.redis.resouce.manager.ResourceManager;
import org.springframework.stereotype.Service;

@Service
public class ResourceService {
    public void addCount(Count count){
        if (count != null){
            ResourceManager.getInstance().addCount(count.getCount());
        }
    }

    public void minusCount(Count count){
        if (count != null) {
            ResourceManager.getInstance().minusCount(count.getCount());
        }
    }

    public Count getCount()
    {
        Count count = new Count();
        count.setCount(ResourceManager.getInstance().getCount());
        return count;
    }

    public void initCount(Count count){
        if (count != null) {
            ResourceManager.getInstance().initCount(count.getCount());
        }
    }
}

编码完成后运行 

出现该界面服务器运行正常，打开postman

服务提供了三个接口：

URL都是：/me/count 只是分PUT、POST和GET，其中PUT用于初始化，POST用于修改（这里修改是累加），GET用于查询。

下面使用POSTMan进行测试：

查询接口，服务启动，count默认就是0：

再新开一个窗口测试put接口输入以下代码，返回值为1则表示成功：

接下来返回get接口访问web，count值为100

再新开一个窗口测试post能否正常修改，返回值为1，修改成功！

接下来返回get接口测试一下，count为130，修改成功！
