security工作笔记003---SpringSecurity框架启动报错.bcrypt.BCryptPasswordEncoder' that could not be found.

醉了，一般这个注入不都是在类顶上注入嘛，这个可好，跑到

ScAuthApplication 中去注入了。。搞了半天，也记录一下吧

1.首先我在这个类中用到了：

E:\IdeaWkSpace\SmartCommunity\sc-auth\src\main\java\cn\gov\rongcheng\scauth\security\WebSecurityConfig.java

@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
    // 使用自定义身份验证组件
    auth.authenticationProvider(new CustomAuthenticationProvider(userDetailsService,bCryptPasswordEncoder));
}

但是微服务启动报错，错误如标题：

package cn.gov.rongcheng.scauth.security;


import cn.gov.rongcheng.scauth.filter.JWTAuthenticationFilter;
import cn.gov.rongcheng.scauth.filter.JWTLoginFilter;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private UserDetailsService userDetailsService;

    private BCryptPasswordEncoder bCryptPasswordEncoder;  //这里可以看到，根本没有注入啊，但是还能跑，刚开始我觉得就不对劲啊,去看了一下jar包，springsecurity 4.2.7，这个也挺奇怪，导入了两个，一个是springsecurity.core这个jar中有个
crypto，然后，还有一个独立的springsecurity.crypto的jar包，而且路径一样的，我就以为是jar冲突了，其实不是，这货，在启动类
E:\IdeaWkSpace\SmartCommunity\sc-auth\src\main\java\cn\gov\rongcheng\scauth\ScAuthApplication.java
这个里面，注入的。。。。。。奇葩用法，郁闷

    public WebSecurityConfig(UserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.userDetailsService = userDetailsService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

            .and()
            .addFilter(new JWTLoginFilter(authenticationManager()))
            .addFilter(new JWTAuthenticationFilter(authenticationManager()))
            .logout() // 默认注销行为为logout，可以通过下面的方式来修改
            .logoutUrl("/logout")
            .logoutSuccessUrl("/login")
            .permitAll();// 设置注销成功后跳转页面，默认是跳转到登录页面;
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        // 使用自定义身份验证组件
        auth.authenticationProvider(new CustomAuthenticationProvider(userDetailsService,bCryptPasswordEncoder));
    }

    }


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