　　　　　　　　　　　　　　Spring添加Junit4支持

Spring框架提供了Test模块，极大简化了项目开发的测试。下面总结一下Spring中Junit的使用：

1.引入Spring核心容器模块，让Spring容器创建管理我们的Bean

　　　　

　　

2.引入Spring的Test模块

　　 

3.编码测试

User的设计

package com.heima_jdbctemplate_c3p0;
/**
 * 标准JavaBean
 * @author GGR
 *
 */
public class User {
    @Override
    public String toString() {
        // TODO Auto-generated method stub
        return super.toString();
    }
    private Integer _id;//用户id
    private String username;//用户名
    private String userpwd;//用户密码

    public User(){}
    public User(String username,String userpwd){
        this.username = username;
        this.setUserpwd(userpwd);
    }
    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getUserpwd() {
        return userpwd;
    }
    public void setUserpwd(String userpwd) {
        this.userpwd = userpwd;
    }
    public Integer get_id() {
        return _id;
    }
    public void set_id(Integer _id) {
        this._id = _id;
    }
}

 

UserDao设计

package com.heima_jdbctemplate_c3p0;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.simple.ParameterizedBeanPropertyRowMapper;
import org.springframework.stereotype.Repository;

import com.heima_jdbctemplate_dbcp.User;

@Repository("userdao")
public class UserDao{
    @Resource(name="jdbctemplate")
    private JdbcTemplate jdbcTemplate;
    public List<User> getAll(){
        return jdbcTemplate.query("select* from t_user",ParameterizedBeanPropertyRowMapper.newInstance(User.class));        
    }
}

jdbc配置文件jdbcinfo.properties

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/spring_database
jdbc.user=root
jdbc.password=362427gg
