eclipse搭建mybatis的环境

1.首先创建一个web工程

2.导入mybatis的jar包

3.创建一个xxx.properties文件里面写

（1）我这里是mysql 8 如果是mysql5，driver就不一样

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybbs?serverTimezone=Asia/Shanghai
jdbc.userName=root
jdbc.passWord=123456

4.创建一个mybatis的xxx.xml的核心配置文件

5.创建一个实体类

例如：

public class Board {
private Integer boardId;
private String boardName;
private Integer parentId;
public Integer getBoardId() {
	return boardId;
}
public void setBoardId(Integer boardId) {
	this.boardId = boardId;
}
public String getBoardName() {
	return boardName;
}
public void setBoardName(String boardName) {
	this.boardName = boardName;
}
public Integer getParentId() {
	return parentId;
}
public void setParentId(Integer parentId) {
	this.parentId = parentId;
}
public Board() {
	
}
public Board(Integer boardId, String boardName, Integer parentId) {
	super();
	this.boardId = boardId;
	this.boardName = boardName;
	this.parentId = parentId;
}
@Override
public String toString() {
	return "Board [boardId=" + boardId + ", boardName=" + boardName + ", parentId=" + parentId + "]";
}

}

6.创建一个xxxMapper.xml的文件

6.写测试文件
