Spring Sercurity介绍

        在web应用开发中，安全无疑是十分重要的，选择Spring Security来保护web应用是一个非常好的选择。Spring Security是一个能够为基于Spring的企业应用系统提供声明式的安全访问控制解决方案的安全框架。

Spring Sercurity项目搭建

这是我们最基本的架构图：

• security：父工程

• security-core：核心业务逻辑

• security-borowser：浏览器相关特定代码

• security-app：app相关特定代码

• security-demo：样例程序

        </plugins>
        <finalName>demo</finalName>
    </build>

application.properties文件

        由于我们引入了mysql的驱动包和spring-session，那么我们需要在security-demo工程配置jdbc连接信息，反则项目启动会报错。

spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.url= jdbc:mysql://127.0.0.1:3306/security-demo?useUnicode=yes&characterEncoding=UTF-8&useSSL=false
spring.datasource.username = root
spring.datasource.password = xxxx
 
 
# 暂且关闭spring-session，后续会继续见解它的使用
spring.session.store-type = none
# 项目访问端口server.port = 80

        现在我们可以在security-demo工程中开始写我们的spring boot的启动类和第一个Controller。

@SpringBootApplication
@RestController
public class DemoApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class);
    }
}

@RestController
public class HelloController {
    @GetMapping("/hello")
    public String hello(){
        return "hello spring security";
    }
}

最终访问结果

我们访问http://localhost/hello：

        会弹出spring-security的用户验证对话框，这是在spring环境下的security默认配置，我们可以通过一写的方式关闭:

# 关闭spring-security身份验证
security.basic.enabled = false
