小编Jcx*_* Jc的帖子

所以我有以下内容:

public interface  MyService {

    @PreAuthorize("hasPermission(T(Name).OBJ, T(Action).GET)")
    MyObj getObj(String id);
}

@Service
public class MyServiceImpl implements MyService {

    @Override
    @Transactional
    public MyObj getObj(String id){

        return dao.get(id);
    }
}

@Controller
public class MyController {

    @Resource(name="myServiceImpl")
    private MyService service;

    public MyObj getObj(String id){

       return service.getObj(id);
    }
}

getObj(id)调用该方法时,首先将所有内容包装在事务中,然后检查授权.是否可以保留此配置并首先让Spring检查授权,然后在用户获得授权的情况下创建事务？

我花了很多钱寻找答案,找不到任何东西.

谁能解释以下内容:

package com.foo.bar;

import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.ProtocolException;
import java.net.URL;
import org.springframework.util.FileCopyUtils;

public class ATest {

    public static void main(String[] args) throws Exception {
       try {
           final String payload = "{\"parentExecutor\":\"foo1233\"}";
           URL url = new URL("http://localhost/notes");
           final HttpURLConnection connection = (HttpURLConnection) url.openConnection();
           connection.setRequestMethod("DELETE");
           connection.setRequestProperty("Accept", "application/json");
           connection.setRequestProperty("Content-Type", "application/json");
           FileCopyUtils.copy(payload.getBytes(), connection.getOutputStream());
           connection.connect();
           final InputStream is = connection.getInputStream();
           int b = is.read();
           String result = "";
           while (b != -1) {
               result += (char) b;
               b = is.read();
           }
           System.out.println(connection.getResponseCode());
           System.out.println(result);
           is.close(); …
