step2：自动注入TransactionTemplate对象

1 import org.springframework.transaction.support.TransactionTemplate;    2 @Autowired3 private TransactionTemplate transactionTemplate;

step3：使用execute方法对事务进行管理

1 transactionTemplate.execute(new TransactionCallbackWithoutResult() {2                 3                 @Override4                 protected void doInTransactionWithoutResult(TransactionStatus arg0) {5                     String s = userService.newUser(user,currentUserId);6                     User newUser=userService.getUser(user.getUsername());7                     roleService.createRoleUser(newUser.getUserId(), rolesId);8                 }9             });

完整流程如下：

1 package com.superb.mips.terminal.rest.controller; 2  3 import java.util.HashMap; 4  5 import org.apache.commons.lang3.StringUtils; 6 import org.springframework.beans.factory.annotation.Autowired; 7 import org.springframework.stereotype.Controller; 8 import org.springframework.transaction.TransactionStatus; 9 import org.springframework.transaction.annotation.Transactional;10 import org.springframework.transaction.support.TransactionCallbackWithoutResult;11 import org.springframework.transaction.support.TransactionTemplate;12 import org.springframework.web.bind.annotation.RequestMapping;13 import org.springframework.web.bind.annotation.ResponseBody;14 15 import com.superb.mips.system.domain.User;16 import com.superb.mips.system.service.inf.RoleService;17 import com.superb.mips.system.service.inf.UserService;18 19 20 @Controller21 @RequestMapping("api/users")22 public class RestUserController {23     @Autowired24     private UserService userService;25     &orgName=中国移动&orgId=126     @Autowired27     private RoleService roleService;28     @Autowired29     private TransactionTemplate transactionTemplate;30 31     @RequestMapping(value = "/createUsers.json")32     @ResponseBody33     @Transactional34     public HashMap
     
       createUser(final User user,final int currentUserId,final String rolesId) {35         HashMap
      
        map = new HashMap
       
        ();36         String[] strAry=rolesId.split(",");37         if(strAry.length==0){38             map.put("result", 1);39             map.put("description", "请绑定角色");40             return map;41         }else{42             for(int i=0;i
