一、mybatis
1、添加jar包
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.4.4</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.42</version>
</dependency>
<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm</artifactId>
<version>5.2</version>
</dependency>
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>3.2.4</version>
</dependency>
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
2、写一个Students的简单示例
1、定义一个表
DROP TABLE IF EXISTS `students`;
CREATE TABLE students (
id int(5) PRIMARY KEY,
name varchar(10) ,
sal double(8,2) ,
)
2、写一个对应的实体类
public class Students implements Serializable {
private Integer id;
private String name;
private Double sal;
public Students() {
}
public Students(Integer id, String name, Double sal) {
super();
this.id = id;
this.name = name;
this.sal = sal;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
