一、 集成SpringBoot

1.1  Spring Boot 介绍

1.2 创建maven工程

1）创建maven工程 security-spring-boot，工程结构如下：

2）引入以下依赖：

<?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"> <modelVersion>4.0.0</modelVersion> <groupId>com.itheima.security</groupId> <artifactId>security‐springboot</artifactId> <version>1.0‐SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring‐boot‐starter‐parent</artifactId> <version>2.1.3.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF‐8</project.build.sourceEncoding>         <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <!‐‐ 以下是>spring boot依赖‐‐> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring‐boot‐starter‐web</artifactId> </dependency> <!‐‐ 以下是>spring security依赖‐‐> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring‐boot‐starter‐security</artifactId> </dependency> <!‐‐ 以下是jsp依赖‐‐> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet‐api</artifactId> <scope>provided</scope> </dependency> <!‐‐jsp页面使用jstl标签 ‐‐> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring‐boot‐starter‐tomcat</artifactId> <scope>provided</scope> </dependency> <!‐‐用于编译jsp ‐‐> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat‐embed‐jasper</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.0</version> </dependency> </dependencies> <build> <finalName>security‐springboot</finalName> <pluginManagement> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7‐maven‐plugin</artifactId> <version>2.2</version> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven‐compiler‐plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <artifactId>maven‐resources‐plugin</artifactId> <configuration> <encoding>utf‐8</encoding> <useDefaultDelimiters>true</useDefaultDelimiters>                         <resources> <resource> <directory>src/main/resources</directory>                                 <filtering>true</filtering> <includes> <include>**/*</include> </includes> </resource> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </configuration> </plugin> </plugins> </pluginManagement> </build> </project> 

1.3spring容器配置

SpringBoot工程启动会自动扫描启动类所在包下的所有Bean，加载到spring容器

在resources下添加application.properties，内容如下：

server.port=8080
server.servlet.context‐path=/security‐springboot
spring.application.name = security‐springboot

2）Spring Boot 启动类

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

1.4ServletContext配置

由于Springbootstarter自动装配机制，这里无需使用@EnableWebMvc与@ComponentScan，WebConfig如下

 @Configuration
public class WebConfig implements WebMvcConfigurer {//默认Url根路径跳转到/login，此url为spring security提供@Overridepublic void addViewControllers(ViewControllerRegistry registry) {registry.addViewController("/").setViewName("redirect:/login");    }
}

视频解析器配置在application.properties中

spring.mvc.view.prefix=/WEB‐INF/views/ 
spring.mvc.view.suffix=.jsp 

1.5安全配置

由于Springbootstarter自动装配机制，这里无需使用@EnableWebSecurity，WebSecurityConfig内容如下

 @Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {//内容跟Spring security入门程序一致
}

1.6测试

LoginController的内容同同Springsecurity入门程序。

 @RestController
public class LoginController {//内容略..跟Spring security入门程序保持一致}
