spring-security（四）java config-sample之jdbc

前言
  本篇文章我们举例说明在spring-security中利用mysql来存储用户信息和权限信息，示例采用security默认提供的DDL。

环境：
  spring-boot版本：1.5.4.RELEASE

1.项目工程结构




2.配置类SecurityConfig.java

/**
 * 
 */
package nariis.chengf.security.samples.javaconfig.jdbc;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

import com.alibaba.druid.pool.DruidDataSource;

/**
 * @author: 作者： chengaofeng
 * @date: 创建时间：2018-01-09 08:31:44
 * @Description: TODO
 * @version V1.0
 */
@EnableWebSecurity
public class SecurityConfig {
	@Bean
	public DruidDataSource dataSource() {
		DruidDataSource dataSource = new DruidDataSource();
		dataSource.setDriverClassName("com.mysql.jdbc.Driver");
		dataSource.setUsername("root");
		dataSource.setPassword("sso");
		dataSource.setName("chengf");
		dataSource.setUrl("jdbc:mysql://localhost:3306/chengf?useUnicode=true&characterEncoding=UTF-8");
		dataSource.setMaxActive(20);
		dataSource.setInitialSize(1);
		dataSource.setMaxWait(60000);
		dataSource.setMinIdle(1);
		dataSource.setTimeBetweenEvictionRunsMillis(60000);
		dataSource.setMinEvictableIdleTimeMillis(300000);
		dataSource.setValidationQuery("select 'x'");
		dataSource.setPoolPreparedStatements(true);
		dataSource.setMaxPoolPreparedStatementPerConnectionSize(20);
		return dataSource;
	}

	@Autowired
	public void configureGlobal(AuthenticationManagerBuilder auth, DataSource dataSource) throws Exception {
		auth.jdbcAuthentication().dataSource(dataSource);
	}
}

数据源的配置用了druid。

3.数据库表结构，因为采用的是spring-security默认的ddl，所以要创建默认的user和authorities,spring 为我们提供了默认表对应的建表语句，在spring-security-core-*.jar包的org.springframework.security.core.userdetails.jdbc目录下

create table users(username varchar_ignorecase(50) not null primary key,password varchar_ignorecase(500) not null,enabled boolean not null);
create table authorities (username varchar_ignorecase(50) not null,authority varchar_ignorecase(50) not null,constraint fk_authorities_users foreign key(username) references users(username));
create unique index ix_auth_username on authorities (username,authority);

实际创建时，varchar_ignorecase类型时没有的，改成varchar即可



4.接着插入我们测试用的数据




5.启动类SecurityJdbcApp.java

package nariis.chengf.security.samples.javaconfig.jdbc;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Hello world!
 *
 */
@SpringBootApplication
public class SecurityJdbcApp 
{
    public static void main( String[] args )
    {
        SpringApplication.run(SecurityJdbcApp.class, args);
    }
}

6.项目的pom.xml

7.index.html代码

<!DOCTYPE html>
<html>
<head>
<title>Static</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
	hello jdbc!
</body>
</html>

8.启动项目
选中启动类，选择Run As -> Java Application
启动后在浏览器中输入 http://localhot:8080/index.html,如果一切正常，我们会被重定向到login页面，输入我们插入库中的测试用户名和密码


点击login后就会重定向到index.html页面



到此，我们jdbc的简单示例就完成了。后续我们还会进一步探讨采用jdbc来做认证存储，包括自定义数据表结构，用户权限继承等等功能。
