1.Security

1.1.简介

Spring Security is a powerful and highly customizable authentication and access-control framework. It is the de-facto standard for securing Spring-based applications.

Spring Security is a framework that focuses on providing both authentication and authorization to Java applications. Like all Spring projects, the real power of Spring Security is found in how easily it can be extended to meet custom requirements

1.2.特点

对身份验证和授权的全面和可扩展的支持
防止会话固定，点击劫持，跨站点请求伪造等攻击
Servlet API集成
可选与Spring Web MVC集成
等等

2.Spring boot整合Security

此处我们使用Spring官网的示例做一个简单的Demo

2.1.结构图

此处先展示一下接下来的Demo的结构图

2.2.准备

在pom.xml中添加如下配置，引入对Spring Security的依赖。

        <dependency>
           <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
复制代码

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests().antMatchers("/", "/home1").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage("/login1").permitAll()
                .and()
                .logout().permitAll();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .inMemoryAuthentication()
                .withUser("user").password("password").roles("USER")
                .and()
                .passwordEncoder(new CustomPasswordEncoder());
    }
}
复制代码

public class CustomPasswordEncoder implements PasswordEncoder {
    @Override
    public String encode(CharSequence charSequence) {
        return charSequence.toString();
    }

    @Override
    public boolean matches(CharSequence charSequence, String s) {
        return s.equals(charSequence.toString());
    }
}
复制代码

@Configuration
public class MvcConfig implements WebMvcConfigurer {
    @Override
    public void addViewControllers(ViewControllerRegistry registry){
        registry.addViewController("/home1").setViewName("/home");
        registry.addViewController("/").setViewName("/home");
        registry.addViewController("/hello1").setViewName("hello");
        registry.addViewController("/login1").setViewName("login");
    }
}
