Myeclipse简单地链接数据库

首先新建一个web project

1、mysql的链接jar包：http://download.csdn.net/download/qq_34926773/9968477

2、在 Eclipse 的 Java 工程中新建一个 lib 文件夹，将所准备的 JAR 包复制进去。

3、右键该 JAR 包：Build Path --> Add to Build Path 

private String jdbcDriver = "com.mysql.jdbc.Driver";
private String jdbcUrl = "jdbc:mysql://localhost:3306/test";
private String jdbcUser = "root";
private String jdbcPass = "123456";

//添加员工
public boolean saveEmp(){
boolean flag = false;
Connection conn = null;
Statement st = null;
try {
//加载驱动
Class.forName(jdbcDriver);
conn = DriverManager.getConnection(jdbcUrl,jdbcUser,jdbcPass);
String sql = "insert into emp values('7777','LZH','manger',"+null+",'2017-10-1','90000','10000','10')";
st = conn.createStatement();
int result = st.executeUpdate(sql);
if(result > 0){
flag = true;
}
} catch (Exception e) {
e.printStackTrace();
}
return flag;
}
