# 1、需要序列化类 #

/**   
     * @Title: ReqIn.java 
     * @Package com.spring.pro.utils.fastjson 
     * @Description:  
     * @author ybwei  
     * @date 2018年10月8日 上午11:23:44 
     * @version V1.0   
     */
    public class ReqIn<T> {
    
    	private String token;
    	private T data;
    	
    	public ReqIn(String token, T data) {
    		super();
    		this.token = token;
    		this.data = data;
    	}
    	public ReqIn() {
    		super();
    	}
    	public String getToken() {
    		return token;
    	}
    	public void setToken(String token) {
    		this.token = token;
    	}
    	public T getData() {
    		return data;
    	}
    	public void setData(T data) {
    		this.data = data;
    	}
    }

# 2、定义model #

/**   
     * @Title: User.java 
     * @Package com.spring.pro.utils.fastjson 
     * @Description:  
     * @author ybwei  
     * @date 2018年10月8日 上午11:26:10 
     * @version V1.0   
     */
    public class User {
    
    	private String id;
    	private int age;
    	
    	
    	public User() {
    		super();
    	}
    	public User(String id, int age) {
    		super();
    		this.id = id;
    		this.age = age;
    	}
    	public String getId() {
    		return id;
    	}
    	public void setId(String id) {
    		this.id = id;
    	}
    	public int getAge() {
    		return age;
    	}
    	public void setAge(int age) {
    		this.age = age;
    	}
    }

# 3、测试 #

import java.lang.reflect.Type;
    
    import org.junit.Test;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    import com.alibaba.fastjson.JSON;
    import com.alibaba.fastjson.TypeReference;
    
    /**
     * @Title: GenericityTest.java
     * @Package com.spring.pro.utils.fastjson
     * @Description:
     * @author ybwei
     * @date 2018年10月8日 上午11:21:50
     * @version V1.0
     */
    public class GenericityTest {
    	private Logger logger = LoggerFactory.getLogger(getClass());
    
    	@Test
    	public void parseObject() {
    		User user = new User("1", 12);
    		ReqIn<User> req = new ReqIn<>("token", user);
    		String str = JSON.toJSONString(req);
    		logger.info("str:{}", str);
    		
    		Type type = new TypeReference<ReqIn<User>>() {}.getType();
    		ReqIn<User> req2 = JSON.parseObject(str, type);
    		logger.info("req2:{}",JSON.toJSONString(req2));
    	}
    }
