mybatis01-1测试

首先需要数据源信息和日志文件

然后一个SQLMapConfig.xml配置文件连接数据库并且映射后一个xml文件，另一个xml文件写入SQL语句，

最后text测试文件读取第一个配置文件，放到SQLSessionFactory工厂，SQLSession进行读取

jdbc.properties

log4j.properties

User.java

package pojo;

public class User {
    private String phone;
    private String uname;
    private String upwd;
    private String email;
    private int role;
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public void setUname(String uname) {
        this.uname = uname;
    }
    public void setUpwd(String upwd) {
        this.upwd = upwd;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public void setRole(int role) {
        this.role = role;
    }
    
    
    public String getPhone() {
        return phone;
    }
    public String getUname() {
        return uname;
    }
    public String getUpwd() {
        return upwd;
    }
    public String getEmail() {
        return email;
    }
    public int getRole() {
        return role;
    }
    @Override
    public String toString() {
        return "User [phone=" + phone + ", uname=" + uname + ", upwd=" + upwd + ", email=" + email + ", role=" + role
                + "]";
    }
