spring4整合mybatis3

开发环境搭建

安装Jdk和环境变量配置java_home、path和classpath
安装eclipse的jre环境
安装tomcat8
安装mysql5以上数据库

所需jar包

准备数据库资源

完成配置文件

db.properties

dataSource.driverClass=com.mysql.jdbc.Driver
dataSource.jdbcUrl=jdbc:mysql://127.0.0.1:3306/mybatis
dataSource.user=root
dataSource.password=root
dataSource.maxPoolSize=20
dataSource.maxIdleTime = 1000
dataSource.minPoolSize=6
dataSource.initialPoolSize=5

持久层实现

User.java

public class User implements Serializable{

	private String phone;		// 电话
	private String address;		// 地址
	
	public User() {
		super();
		// TODO Auto-generated constructor stub
	}
	省略getter和setter

Book.java

public class Book implements Serializable{
	
	private Integer id;				// id
