Hibernate初级例子

Hibernate初级

在Myeclipse部署

实体类：

package com.entity;

/**

* Teacher entity. @author MyEclipse Persistence Tools

*/

public class Teacher implements java.io.Serializable {

// Fields

private int tids;

private String tname;

private Double tprice;

// Constructors

/** default constructor */

public Teacher() {

}

public Teacher(String tname, Double tprice) {

super();

this.tname = tname;

this.tprice = tprice;

}

public Teacher(int tids, String tname) {

super();

this.tids = tids;

this.tname = tname;

}

public Teacher(int tids, String tname, Double tprice) {

super();

this.tids = tids;

this.tname = tname;

this.tprice = tprice;

}

// Property accessors

public int getTids() {

return this.tids;

}

public void setTids(int tids) {

this.tids = tids;

}

public String getTname() {

return this.tname;

}

public void setTname(String tname) {

this.tname = tname;

}

public Double getTprice() {

return this.tprice;

}

public void setTprice(Double tprice) {

this.tprice = tprice;

}

}
