通过JAVA的main方法直接访问spring mvc 的controller

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import net.sf.json.JSONArray;

public class HttpTest {
    public static void addLog() throws IOException {
        String url = "http://127.0.0.1:8080/server/httptest";//路径一定要对否则通不过
        // 创建默认的httpClient实例.
        HttpClient client = new DefaultHttpClient();
        // 创建httppost通过post方式访问
        HttpPost httppost = new HttpPost(url);
        // 创建参数队列
        List slist = new ArrayList<>();
        
        Student student = new Student();
        student.setId("1");
        student.setName("名称ss");
        slist.add(student);
        //将数组对象转换为json数组
        JSONArray jsonArray = JSONArray.fromObject(slist);

        System.out.println(jsonArray.toString());

        //作为参数发送到controller
        StringEntity entity = new StringEntity(jsonArray.toString(),"utf-8");
        entity.setContentEncoding("UTF-8");    
        entity.setContentType("application/json");    
        httppost.setEntity(entity);  
        HttpResponse response = client.execute(httppost);
    }
    
    public static void main(String args[]) throws ClientProtocolException, IOException{
        HttpTest.addLog();
    }

}

//Student.java代码

public class Student {
    String name;
    String id;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

}

//controller代码

@Controller
public class HttpTestController {
    @RequestMapping(value = "/httptest", method = RequestMethod.POST)
    @ResponseBody

//将Student接收过来，此时过来的是Json数组，里面对应的属性要和Student里面的保持一致，Spring可以将JSON数组自动转换为对象数组

//但是需要在Spring里面配置才能转，否则不识别

//如何配置在下面有介绍

public void httptest(@RequestBody Student[] data) {
        System.out.println(data[0].getId()+"-------------");
        
    }
}
