服务器token

// User.java
    public class User{ 
        private String email;
        private String userName;
        private Integer userId;
        private String mobile;
    
        public String getMobile() { 
            return mobile;
        }
    
        public void setMobile(String mobile) { 
            this.mobile = mobile;
        }
    
        public Integer getUserId() { 
            return userId;
        }
    
        public void setUserId(Integer userId) { 
            this.userId = userId;
        }
    
        public String getEmail() { 
            return email;
        }
    
    
        public void setEmail(String email) { 
            this.email = email;
        }
    
        public void setUserName(String userName) { 
            this.userName = userName;
        }
    
        public String getUserName() { 
            return userName;
        }
    }
    // Constant.java
    public final class Constant { 
        /** * 用户SESSION标识 */
        public static final String USER_SESSION_NAME      = "user";
    }
    // UserInfoController.java
    
    @Controller
    @SessionAttributes(Constant.USER_SESSION_NAME)
    public class UserInfoController{ 
    	
    	@RequestMapping(value = Path.USER_LOGIN, method = RequestMethod.POST)
        public String login(final Model model){ 
       			User user = new User();
       			...
                model.addAttribute(Constant.USER_SESSION_NAME, user);
        		// 设置token
        }
        
        @RequestMapping(value = Path.USER_RECOMMENDATION_DATA, method = RequestMethod.POST)
        @ResponseBody
        public Map<String, Object> recommendationNeedsDatas(@ModelAttribute(Constant.USER_SESSION_NAME)final User user){ 
        	...
        }
        // 使用token 
    }

核心：  
1、@SessionAttributes(Constant.USER\_SESSION\_NAME) 标记表示支持token  
2、设置token

model.addAttribute(Constant.USER_SESSION_NAME, user);

3、使用token

// 在请求参数中传入
    @ModelAttribute(Constant.USER_SESSION_NAME)
