springBoot总结:

ssm基本的依赖:

<dependencies>
<!--添加依赖thymeleaf 可以访问html页面-->
<!--<dependency>

<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<!--<scope>provided</scope>-->
</dependency>
<!--独立发布到tomcat-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<!--热部署依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
</dependency>
<!-- spring boot的web支持-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--mybatis-spring桥梁-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>
<!--mysql驱动包-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<!--aop-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
<!--jdbc-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>

</dependencies>

模板引擎:

1:jsp:

依赖:

    <!--对jsp访问的支持-->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>

controller层页面跳转:

2:html页面的支持:(需要 thymeleaf  jar包)

依赖:

 <!--模板引擎thmeleaf对HTML的支持-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

controller层页面跳转:

3、springBoot在idea中如何热部署(即启动项目后,修改方法内部或静态页面不需要重启):

1.热部署的Maven依赖:

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
</dependency>
2. Alt+Ctrl+Shift+/ :设置

3:找到Settings的 compiler项,勾选Build project automatically

4:springBoot项目如何打成war包 发布:

1.将spring-boot-starter-tomcat的范围设置为provided

设置为provided是在打包时会将该包排除,因为要放到独立的tomcat中运行,是不需要的。

        <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

2.修改启动类:

继承 springBootServletInitializer 类 重写 configure方法:

3:打包:

打包完之后在项目保存的文件夹找到target包中的war包复制到tomcat中即可。
