+# spring boot 整合 tomcat
+
+## 一、说明
+
+#### 1.1 项目结构说明
+
+spring boot 整合 tomcat 后支持jsp 的使用（内置容器默认是不支持jsp），所以项目整合后采用jspController 跳转到show.jsp测试整合是否成功。
+

+
+#### 1.2 项目主要依赖
+
+```xml
+<dependency>
+    <groupId>org.springframework.boot</groupId>
+    <artifactId>spring-boot-starter-web</artifactId>
+    <!--排除内置容器依赖 使用外部tomcat容器启动-->
+    <exclusions>
+        <exclusion>
+            <groupId>org.springframework.boot</groupId>
+            <artifactId>spring-boot-starter-tomcat</artifactId>
+        </exclusion>
+    </exclusions>
+</dependency>
+<dependency>
+    <!--使用外置容器时候SpringBootServletInitializer 依赖此包 -->
+    <groupId>javax.servlet</groupId>
+    <artifactId>servlet-api</artifactId>
+    <version>2.5</version>
+    <scope>provided</scope>
+</dependency>
+```
+
+## 二、整合 tomcat
+
+#### 2.1 修改启动类，继承自SpringBootServletInitializer，并覆盖重写其中configure方法
+
+```java
+/**
+ * 如果用外置tomcat,启动报错java.lang.NoClassDefFoundError: javax/el/ELManager
+ * 是因为tomcat 7.0 el-api包中没有ELManager类 , 切换tomcat 为8.0 以上版本即可
+ */
+@SpringBootApplication
+public class SpringBootTomcatApplication extends SpringBootServletInitializer {
+
+
+    @Override
+    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
+        //传入SpringBoot应用的主程序
+        return application.sources(SpringBootTomcatApplication.class);
+    }
+
+    public static void main(String[] args) {
+        SpringApplication.run(SpringBootTomcatApplication.class, args);
+    }
+
+}
+```
+
+#### 2.2 在application.yml 中指定访问视图文件的前缀和后缀 
+
+```yml
+spring:
+  mvc:
+    view:
+      prefix: /WEB-INF/jsp/
+      suffix: .jsp
+```
+
+#### 2.3 新建controller和show.jsp 测试整合是否成功
+
+```java
+@Controller
+@RequestMapping("index")
+public class JspController {
+
+    @RequestMapping
+    public String jsp(Model model){
+        Programmer programmer = new Programmer("heibai", 21, 1298.31f, LocalDate.now());
+        model.addAttribute("programmer",programmer);
+        return "show";
+    }
+}
+```
+
+```jsp
+<%@ page contentType="text/html;charset=UTF-8" language="java" %>
+<html>
+<head>
+    <title>programmer</title>
+    <link rel="stylesheet" href="${pageContext.request.contextPath}/css/show.css">
+</head>
+<body>
+<ul>
+    <li>姓名: ${programmer.name}</li>
+    <li>年龄: ${programmer.age}</li>
+</ul>
+</body>
+</html>
+```
+
