SpringBoot前后端分离_集成_SpringSecurity_简单实现
1.新建SpringBoot项目,可以使用idea,快速创建
file-create-project->选择web,sql:mysql mybatis这样就可以了
2.application.properties
spring.profiles.active=dev
# 所有环境通用的配置，放在这里

3.application-dev.properties
# 开发环境配置
# 数据源配置，请修改为你项目的实际配置
spring.datasource.url=jdbc:mysql://172.19.128.30:3306/test_lidw?useUnicode=true&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#指定服务端口
server.port=8089

4.
com.springsecurity.demo.controller.HelloController
package com.springsecurity.demo.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
// 省略之前的内容...
@RequestMapping("/login")
public String login() {
return "login";
}

// 省略之前的内容...
@RequestMapping("/hello")
public String hello() {
return "hello";
}
}

--------------------------------------
5.
com.springsecurity.demo.security.WebSecurityConfig

package com.springsecurity.demo.security;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder ;
@Configuration
@EnableWebSecurity//通过@EnableWebSecurity注解开启Spring Security的功能
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
//通过@EnableWebSecurity注解开启Spring Security的功能
@Override//configure(HttpSecurity http)方法
protected void configure(HttpSecurity http) throws Exception {
//通过authorizeRequests()定义哪些URL需要被保护、哪些不需要被保护。
//例如以上代码指定了/和/home不需要任何认证就可以访问，其他的路径都必须通过身份验证。
http
.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")//通过formLogin()定义当需要用户登录时候，转到的登录页面。
.permitAll()
.and()
.logout()
.permitAll();
}

//configureGlobal(AuthenticationManagerBuilder auth)方法，在内存中创建了一个用户，
// 该用户的名称为user，密码为password，用户角色为USER。
// 在完成了Spring Security配置之后，我们还缺少登录的相关内容。
//HelloController中新增/login请求映射至login.html

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER");
}

}

-------------------------------
6.com.springsecurity.demo.DemoApplication
package com.springsecurity.demo;

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

@SpringBootApplication
public class DemoApplication {

public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
---------------------------------------------------------

</project>

--------------------------------
写完之后,就可以去访问:
http://localhost:8089/hello
访问的时候,由于没有登录,会自动跳转到登录页面
地址变成:
http://localhost:8089/login
