SPRINGBOOT 第十章

Security

POM加入springsecurity依赖,任何接口都被保护起来了，用户及密码是每次访问随机生成的

手工配置用户名及口令，可以在数据库里面配置或在配置文件里面配置

第一种：配置文件

spring.security.user.password=123

spring.security.user.name=gcmax

spring.security.user.roles=admin

第二种：securityconfg extends websecurityConfigurerAdapter

configure

内存里面配置

密码加密

BCryptPasswordEncoder encoder=new BCryptPasswordEncoder();

encoder.encode("123");

PasswordEncoder passwordEncoder(){

    return NoOpPasswordEncoder.getInstance();, 这里改成return new BCryptPasswordEncoder();

}

方法安全

方法上面加上注解

@PreAuthorize("hasRole('admin')")

public String admin(){

     return "hello admin";
}

@Secured("ROLB_user")

public String user(){

    return "hello user";

}

基于数据库安全认证

            setDetails(request, authRequest);

            return this.getAuthenticationManager().authenticate(authRequest);
