IDEA连接mysql数据库时报错 java.sql.SQLExceptionAccess denied for user ''@'localhost' (using password: YES) 

对这个错误表示蛋疼,由于IDEA智能提示的原因,没有注意看提示的候选项,下意识的选中了name

所以就报 Access denied for user ''@'localhost' (using password: YES) ,修改过访问权限还是不行,仔细核对属性名称,才发现是选的属性不对,将属性修改为username才正常:

测试访问数据库连接:

package com.mydata.springboot;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import javax.sql.DataSource;
import java.sql.Connection;
import java.sql.SQLException;

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringBootDataApplicationTests {

    @Autowired
    DataSource dataSource;
    @Test
    public void contextLoads() throws SQLException {
        System.out.println("数据源class:"+dataSource.getClass());
        try (Connection connection = dataSource.getConnection()) {
            System.out.println("获取数据连接:"+connection);
        }

    }

}

OK!这样显示就说明数据库已经连接成功:
