高级特性 Profile 为了方便多环境开发，springboot简化了profile功能 application-prod.yaml 开发环境配置 server: port: 5001 application-test.yaml 测试环境配置 server: port: 8080 application.yaml 使用profile spring: profiles: active: test或者prod 第二种激活方式， 命令行激活 java -jar xxxx.jar

自动配置原理入门 引导自动加载配置类 @SpringBootConfiguration @EnableAutoConfiguration @ComponentScan(excludeFilters = { @Filter(type = FilterType.CUSTOM, classes = TypeExcludeFilter.class), @Filter(type = FilterType.CUSTOM, classes = AutoConfigurationExcludeFilter.class)

转发和重定向 // 有视图解析器 @Controller @RequestMapping("/t1") public class TestController { @RequestMapping("/test1") public String test(){ return "forward:/WEB-INF/jsp/test1.jsp"; } @RequestMapping("/test3") public String test3(){

SpringMVC执行流程 public class HelloController implements Controller { @Override public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView mv = new ModelAndView(); mv.

Spring整合Mybatis 引入依赖 <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-jdbc</artifactId> <version>2.2.4</version> </dependency> <dependency>

Spring 理念：简化开发 是一个轻量级，非入侵式的框架 控制反转（IOC） 将创建对象过程交给Spring进行管理 面向切面（AOP）不修改源代码进行功能增强 入门案列 创建一个maven项目，导入依赖 <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spri
