### 一、创建一个简单的maven工程spring-boot-security，pom.xml依赖如下： ###

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.1.4.RELEASE</version>
        </parent>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-thymeleaf</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.security</groupId>
                <artifactId>spring-security-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
    
        <properties>
            <java.version>1.8</java.version>
        </properties>
    
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

### 二、创建springmvc配置类MvcConfig.java，并添加视图控制器 ###

package com.szcatic.configurations;
    
    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");
        }
    
    }

### 三、创建安全配置类WebSecurityConfig.java ###

package com.szcatic.configurations;
    
    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();
    	}
    
    	@SuppressWarnings("deprecation")
    	@Bean
    	@Override
    	public UserDetailsService userDetailsService() {
    		UserDetails user = User.withDefaultPasswordEncoder().username("user").password("password").roles("USER")
    				.build();
    		return new InMemoryUserDetailsManager(user);
    	}
    }

### 四、在资源src/main/resources目录下新建文件夹templates，并分别创建文件home.html、hello.html、login.html ###

<!DOCTYPE html>
    <html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://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>

<!DOCTYPE html>
    <html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
          xmlns:sec="http://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>

<!DOCTYPE html>
    <html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
          xmlns:sec="http://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>

###  五、创建引导类Application.java ###

package com.szcatic;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class Application {
    
        public static void main(String[] args) throws Throwable {
            SpringApplication.run(Application.class, args);
        }
    
    }

### 六、启动程序，运行引导类 ###
