I am new to spring. I want to load data in two models Trade and Skill.
Written code sample is here -
Controller Code -

 @PostMapping("/create")
 public String Create(@RequestBody TradeSkill tradeskill) 
 System.out.println(tradeskill);
 return "record is created";
 

Parent Request Body -

class TradeSkill 
 @Autowired
 protected Skill skill;
 @Autowired
 protected Trade trade;

 public TradeSkill() 
 super();
 // TODO Auto-generated constructor stub
 
 @Override
 public String toString() 
 return "TradeSkill [skill=" + skill + ", trade=" + trade + "]";
 

Json is -

 "skill" : 
 "name" : "new skill"
 ,
 "trade" : 
 "trade_name" : "Trade"
 

Console Output is -
TradeSkill [skill=null, trade=null]

What am i doing wrong. Any help would be appreciated.

Please consider doing following:

1. Drop @Autowired from TradeSkill, add getters and setters for trade and skill fields.




2. Make sure that name and tradeName fields within Skill and Trade models respectively also got getters and setters.




3. Fix your request json, replace trade_name with tradeName.

As @Bohdan Levchenko suggested in his answer, classes should look like below:

TradeSkill.java

public class TradeSkill 
 protected Skill skill;
 protected Trade trade;

 public Skill getSkill() 
 return skill;
 

 public void setSkill(Skill skill) 
 this.skill = skill;
 

 public Trade getTrade() 
 return trade;
 

 public void setTrade(Trade trade) 
 this.trade = trade;
 

 @Override
 public String toString() 
 return "TradeSkill [skill=" + skill + ", trade=" + trade + "]";
 

Trade.java

public class Trade 
 private String trade_name;

 public String getTrade_name() 
 return trade_name;
 

 public void setTrade_name(String trade_name) 
 this.trade_name = trade_name;
 

Skill.java

public class Skill 
 private String name;

 public String getName() 
 return name;
 

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

Requested JSON should be like:

 "skill" : 
 "name" : "new skill"
 ,
 "trade" : 
 "trade_name" : "Trade"
