SpringBoot整合Spring Security手动配置用户名密码

部分引自 www.javaboy.org

手动配置用户名密码有两种方式

1.配置文件的方式

在application.properties中

spring.security.user.name=yzn
spring.security.user.password=123
spring.security.user.roles=admin

启动测试

2.采取java代码配置

将application.properties中配置注释掉，新建config目录，新建配置类

package org.javaboy.security.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("yzn").password("123").roles("admin")
                .and()
                .withUser("test").password("123").roles("user");
    }
}

这种方式本来是没有问题的，但是Spring5以后需要对密码进行加密，否则无法正确登录
为了演示方便，我先不加密，但需要使用一个过期方法

package org.javaboy.security.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("yzn").password("123").roles("admin")
                .and()
                .withUser("test").password("123").roles("user");
    }

    @Bean
    PasswordEncoder passwordEncoder(){
        return NoOpPasswordEncoder.getInstance();
    }
}

但两种方式都是写死的，项目中应该结合数据库动态管理
