一、创建工程

新建Maven工程springsecurity-demo，并编辑pom.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.6.RELEASE</version>
        <relativePath/>
    </parent>

    <modelVersion>4.0.0</modelVersion>
    <packaging>war</packaging>
    <name>springsecurity-demo</name>
    <artifactId>springsecurity-demo</artifactId>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</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>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.6.0</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

二、实现代码

1.创建启动类
在项目的src/main/java下创建io.binghe.demo包，并在包下创建DemoApplication类，代码如下：

package io.binghe.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author binghe
 * @version 1.0.0
 * @description 项目启动类
 */
@SpringBootApplication
@EnableAutoConfiguration
public class DemoApplication {
    public static void main(String[] args){
        SpringApplication.run(DemoApplication.class, args);
    }
}

2.在io.binghe.demo包下创建ServletInitializer类，代码如下：

package io.binghe.demo;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

/**
 * @author binghe
 * @version 1.0.0
 * @description Servlet初始化类
 */
public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DemoApplication.class);
    }
}

3.在io.binghe.demo包下创建SpringSecurityConfig类，同于配置SpringSecurity，代码如下：

package io.binghe.demo;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

/**
 * @author binghe
 * @version 1.0.0
 * @description SpringSecurity配置类
 */
@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/").permitAll()
                .anyRequest().authenticated()
                .and()
                .logout().permitAll()
                .and()
                .formLogin();
        http.csrf().disable();
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/js/**", "/css/**", "/images/**");
    }
}

4.创建controller类，新建io.binghe.demo.controller包，在包下创建DemoController类，代码如下：

package io.binghe.demo.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author binghe
 * @version 1.0.0
 * @description 测试使用的Controller
 */
@RestController
public class DemoController {

    @RequestMapping(value = "/")
    public String home(){
        return "hello string boot";
    }

    @RequestMapping(value = "/hello")
    public String hello(){
        return "hello world";
    }
}

三、测试

1.启动工程
运行DemoApplication的main方法

2.测试工程
在浏览器分别访问http://localhost:8080和http://localhost:8080/hello。可以看到可以直接访问http://localhost:8080，而访问http://localhost:8080/hello则需要输入用户名和密码。说明SpringBoot整合SpringSecurity成功。

附图如下：

访问http://localhost:8080效果如下：

访问http://localhost:8080/hello效果如下：
