hibernate一对一外键关联

一、创建实体类

Java代码  

package com.wr.hibernate.entity;  
  
public class Department {  
  
    private int deptId;  
    private String deptName;  
    private Manager mgr;  
  
    public int getDeptId() {  
        return deptId;  
    }  
  
    public Manager getMgr() {  
        return mgr;  
    }  
  
    public void setMgr(Manager mgr) {  
        this.mgr = mgr;  
    }  
  
    public void setDeptId(int deptId) {  
        this.deptId = deptId;  
    }  
  
    public String getDeptName() {  
        return deptName;  
    }  
  
    public void setDeptName(String deptName) {  
        this.deptName = deptName;  
    }  
  
    @Override  
    public String toString() {  
        return "Department [deptId=" + deptId + ", deptName=" + deptName + "]";  
    }  
  
}

Java代码  

package com.wr.hibernate.entity;  
  
public class Manager {  
  
    private int mgrId;  
    private String mgrName;  
    private Department dept;  
  
    public int getMgrId() {  
        return mgrId;  
    }  
  
    public void setMgrId(int mgrId) {  
        this.mgrId = mgrId;  
    }  
  
    public String getMgrName() {  
        return mgrName;  
    }  
  
    public void setMgrName(String mgrName) {  
        this.mgrName = mgrName;  
    }  
  
    public Department getDept() {  
        return dept;  
    }  
  
    public void setDept(Department dept) {  
        this.dept = dept;  
    }  
  
    @Override  
    public String toString() {  
        return "Manager [mgrId=" + mgrId + ", mgrName=" + mgrName + ", dept=" + dept + "]";  
    }  
  
}
