application.yml

server:
  port: 80
spring:
  thymeleaf:
    cache: false #關閉Thymeleaf快取
mengxuegu:
  security:
    authentication:
      loginPage: /login/page  #響應認證（登入）頁面URL
      loginProcessingUrl: /login/form #登入表單提交處理URL
      usernameParameter: name # 登入表單使用者名稱的屬性名
      passwordParameter: pwd # 登入表單密碼的屬性名
      staticPaths: # 靜態資源 "/dist/**", "/modules/**", "/plugins/**"
        - /dist/**
        - /modules/**
        - /plugins/**
 

建立AuthenticationProperties類

package com.mengxuegu.security.properties;

import lombok.Data;

@Data
public class AuthenticationProperties {
    // application.yml 沒配置取預設值
    private String loginPage = "/login/page";
    private String loginProcessingUrl = "/login/form";
    private String usernameParameter = "name";
    private String passwordParameter = "pwd";
    private String[] staticPaths = {"/dist/**", "/modules/**", "/plugins/**"};
    
}
 

建立SecurityProperties類

package com.mengxuegu.security.properties;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component // 不要少了
@ConfigurationProperties( prefix = "mengxuegu.security")
public class SecurityProperties {
    // 將application.yml 中的 mengxuegu.security.authentication 下面的值繫結到此物件中
    private AuthenticationProperties authentication;

    public AuthenticationProperties getAuthentication() {
        return authentication;
    }

    public void setAuthentication(AuthenticationProperties authentication) {
        this.authentication = authentication;
    }
}
 

在SpringSecurityConfig中應用

package com.mengxuegu.security.config;

import com.mengxuegu.security.properties.SecurityProperties;

    @Bean
    public PasswordEncoder passwordEncoder(){

        return new BCryptPasswordEncoder();
    }

    /**

     */
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        String password = passwordEncoder().encode("123456");
        logger.info("加密之後儲存的密碼："+password);
        auth.inMemoryAuthentication().withUser("root").password(password).authorities("ADMIN");
    }

    /**

        ; // 注意不要少了分號
    }

    /**
