Spring 和 SpringBoot 之間到底有啥區(qū)別？

概述

什么是Spring

什么是Spring Boot

從配置分析

Maven依賴

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>5.1.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.1.0.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.0.6.RELEASE</version>
</dependency>

MVC配置

publicclassMyWebAppInitializerimplementsWebApplicationInitializer{

@Override
publicvoid onStartup(ServletContext container) {
AnnotationConfigWebApplicationContext context = newAnnotationConfigWebApplicationContext();
        context.setConfigLocation("com.pingfangushi");
          container.addListener(newContextLoaderListener(context));
ServletRegistration.Dynamic dispatcher = container
.addServlet("dispatcher", newDispatcherServlet(context));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
}
}

@EnableWebMvc
@Configuration
publicclassClientWebConfigimplementsWebMvcConfigurer{
@Bean
publicViewResolver viewResolver() {
InternalResourceViewResolver bean
= newInternalResourceViewResolver();
      bean.setViewClass(JstlView.class);
      bean.setPrefix("/WEB-INF/view/");
      bean.setSuffix(".jsp");
return bean;
}
}

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

配置模板引擎

@Configuration
@EnableWebMvc
publicclassMvcWebConfigimplementsWebMvcConfigurer{

@Autowired
privateApplicationContext applicationContext;

@Bean
publicSpringResourceTemplateResolver templateResolver() {
SpringResourceTemplateResolver templateResolver = newSpringResourceTemplateResolver();
        templateResolver.setApplicationContext(applicationContext);
        templateResolver.setPrefix("/WEB-INF/views/");
        templateResolver.setSuffix(".html");
return templateResolver;
}

@Bean
publicSpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = newSpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());
        templateEngine.setEnableSpringELCompiler(true);
return templateEngine;
}

@Override
publicvoid configureViewResolvers(ViewResolverRegistry registry) {
ThymeleafViewResolver resolver = newThymeleafViewResolver();
        resolver.setTemplateEngine(templateEngine());
        registry.viewResolver(resolver);
}
}

Spring Security 配置

@Configuration
@EnableWebSecurity
publicclassCustomWebSecurityConfigurerAdapterextendsWebSecurityConfigurerAdapter{

@Autowired
publicvoid configureGlobal(AuthenticationManagerBuilder auth) throwsException{
        auth.inMemoryAuthentication()
.withUser("admin")
.password(passwordEncoder()
.encode("password"))
.authorities("ROLE_ADMIN");
}

@Override
protectedvoid configure(HttpSecurity http) throwsException{
        http.authorizeRequests()
.anyRequest().authenticated()
.and()
.httpBasic();
}

@Bean
publicPasswordEncoder passwordEncoder() {
returnnewBCryptPasswordEncoder();
}
}

應(yīng)用程序啟動(dòng)引導(dǎo)配置

Spring 引導(dǎo)配置

SpringBoot 引導(dǎo)配置

@SpringBootApplication
publicclassApplication{
publicstaticvoid main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

/**

 */
publicclassServletInitializerextendsSpringBootServletInitializer{

@Override
protectedSpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}

@Override
publicvoid onStartup(ServletContext servletContext) throwsServletException{
super.onStartup(servletContext);
        servletContext.addListener(newHttpSessionEventPublisher());
}
}
