虽然,我在实际项目中使用的是 shiro 进行权限管理,但 spring boot security 早已大名鼎鼎,虽然他的入门要相对复杂一点,但是设计视乎更加吸引人。

本章节就是以一篇快速入门 spring boot security 来实现如何使用 spring boot security,本示例来源于 Spring官方实例
– java jdk1.8
– maven 3.2+
– spring boot 2.1.6

1 新建 Spring Boot Maven 示例工程项目

  1. File > New > Project,如下图选择 Spring Initializr 然后点击 【Next】下一步
  2. 填写 GroupId(包名)、Artifact(项目名) 即可。点击 下一步
    groupId=com.fishpro
    artifactId=securing
  3. 选择依赖 Spring Web Starter 前面打钩。
  4. 项目名设置为 spring-boot-study-securing.

2 导入依赖 Pom.xml

引入了包括
– thymeleaf
– spring-boot-starter-security

        </plugins>
    </build>

</project>

3 编写示例代码

3.1 WebSecurityConfig-编写配置文件

在配置文件 WebSecurityConfig 是哟合那个注解 @EnableWebSecurity,这样就能在 Web 的应用层使用了。

WebSecurityConfig 继承于 WebSecurityConfigurerAdapter 并重新了方法 configure 和 userDetailsService。

src/main/java/com/fishpro/securing/config/WebSecurityConfig.java

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception{
        http.authorizeRequests()
                .antMatchers("/","/home").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
                .logout()
                .permitAll();
    }

    @Bean
    @Override
    public UserDetailsService userDetailsService(){
        UserDetails user = User.withDefaultPasswordEncoder()
                .username("user")
                .password("password")
                .roles("USER")
                .build();

        return new InMemoryUserDetailsManager(user);
    }
}

3.2 配置mvc

src/main/java/com/fishpro/securing/config/MvcConfig.java

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

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

3.3 前端 登录页面 /login

src/resources/templates/login.html

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="https://www.thymeleaf.org"
      xmlns:sec="https://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head>
    <title>Spring Security Example </title>
</head>
<body>
<div th:if="${param.error}">
    Invalid username and password.
</div>
<div th:if="${param.logout}">
    You have been logged out.
</div>
<form th:action="@{/login}" method="post">
    <div><label> User Name : <input type="text" name="username"/> </label></div>
    <div><label> Password: <input type="password" name="password"/> </label></div>
    <div><input type="submit" value="Sign In"/></div>
</form>
</body>
</html>

3.4 前端 首页 /home

src/resources/templates/home.html

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="https://www.thymeleaf.org" xmlns:sec="https://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head>
    <title>Spring Security Example</title>
</head>
<body>
<h1>Welcome!</h1>

<p>Click <a th:href="@{/hello}">here</a> to see a greeting.</p>
</body>
</html>

3.5 前端 认证成功页面 /hello

src/resources/templates/hello.html

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="https://www.thymeleaf.org"
      xmlns:sec="https://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head>
    <title>Hello World!</title>
</head>
<body>
<h1 th:inline="text">Hello [[${#httpServletRequest.remoteUser}]]!</h1>
<form th:action="@{/logout}" method="post">
    <input type="submit" value="Sign Out"/>
</form>
</body>
</html>
