1、大體步驟

（1）建立Maven web project；

（2）在pom.xml檔案添加依賴；

（3）配置application.properties支援jsp

（4）編寫測試Controller

（5）編寫JSP頁面

（6）編寫啟動類App.java

2、建立SpringInitialzr

3、pom檔案

    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-tomcat</artifactId>            <scope>provided</scope>        </dependency>        <dependency>            <groupId>org.apache.tomcat.embed</groupId>            <artifactId>tomcat-embed-jasper</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</artifactId>            <scope>test</scope>        </dependency>    </dependencies>

4、application.properties檔案

# 頁面預設首碼目錄spring.mvc.view.prefix=/WEB-INF/jsp/# 響應頁面預設尾碼spring.mvc.view.suffix=.jsp# 自訂屬性，可以在Controller中讀取application.hello=Hello GOD

5、Controller檔案

package com.example;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import java.util.Map;/** * Created by Gensis on 2016/9/9. */@Controllerpublic class HelloController {    // 從 application.properties 中讀取配置，如取不到預設值為Hello    @Value("${application.hello:Hello}")    private String hello;    @RequestMapping("/helloJsp")    public String helloJsp(Map<String, Object> map) {        System.out.println("HelloController.helloJsp().hello=" + hello);        map.put("hello", hello);        return "helloJsp";    }}

6、jsp頁面

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>GOD</title></head><body>helloJsp<hr>${hello}</body></html>

7、遇到的問題1、Spring Boot: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean

　　把pom中所有的<scope>provided</scope>注釋掉

2、報404

　　<1>注意controller和restcontroller區別

　　<2>檢查application.properties

　　<3>檢查pom是否缺支援jsp包

3、Failed to introspect annotated methods on class org.springframework.boot.web.support.SpringBootServletInitializer

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.example.SampleWebJspApplication]; nested exception is java.lang.IllegalStateException: Failed to introspect annotated methods on class org.springframework.boot.web.support.SpringBootServletInitializer    at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:187) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.annotation.ConfigurationClassPostProcessor.processConfigBeanDefinitions(ConfigurationClassPostProcessor.java:321) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.annotation.ConfigurationClassPostProcessor.postProcessBeanDefinitionRegistry(ConfigurationClassPostProcessor.java:243) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanDefinitionRegistryPostProcessors(PostProcessorRegistrationDelegate.java:273) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:98) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:681) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:523) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:759) [spring-boot-1.4.0.RELEASE.jar:1.4.0.RELEASE]    at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:369) [spring-boot-1.4.0.RELEASE.jar:1.4.0.RELEASE]    at org.springframework.boot.SpringApplication.run(SpringApplication.java:313) [spring-boot-1.4.0.RELEASE.jar:1.4.0.RELEASE]    at org.springframework.boot.SpringApplication.run(SpringApplication.java:1185) [spring-boot-1.4.0.RELEASE.jar:1.4.0.RELEASE]    at org.springframework.boot.SpringApplication.run(SpringApplication.java:1174) [spring-boot-1.4.0.RELEASE.jar:1.4.0.RELEASE]    at com.example.SampleWebJspApplication.main(SampleWebJspApplication.java:20) [classes/:na]    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_77]    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[na:1.8.0_77]    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_77]    at java.lang.reflect.Method.invoke(Method.java:498) ~[na:1.8.0_77]    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:147) [idea_rt.jar:na]Caused by: java.lang.IllegalStateException: Failed to introspect annotated methods on class org.springframework.boot.web.support.SpringBootServletInitializer    at org.springframework.core.type.StandardAnnotationMetadata.getAnnotatedMethods(StandardAnnotationMetadata.java:163) ~[spring-core-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.annotation.ConfigurationClassParser.doProcessConfigurationClass(ConfigurationClassParser.java:301) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.annotation.ConfigurationClassParser.processConfigurationClass(ConfigurationClassParser.java:237) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:204) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:173) ~[spring-context-4.3.2.RELEASE.jar:4.3.2.RELEASE]    ... 17 common frames omitted

解決方案：添加以下依賴

        <dependency>            <groupId>org.apache.tomcat.embed</groupId>            <artifactId>tomcat-embed-jasper</artifactId>        </dependency>

4、java.lang.NoClassDefFoundError: javax/servlet/ServletContext

Caused by: java.lang.NoClassDefFoundError: javax/servlet/ServletContext    at java.lang.Class.getDeclaredMethods0(Native Method) ~[na:1.8.0_77]    at java.lang.Class.privateGetDeclaredMethods(Class.java:2701) ~[na:1.8.0_77]    at java.lang.Class.getDeclaredMethods(Class.java:1975) ~[na:1.8.0_77]    at org.springframework.core.type.StandardAnnotationMetadata.getAnnotatedMethods(StandardAnnotationMetadata.java:152) ~[spring-core-4.3.2.RELEASE.jar:4.3.2.RELEASE]    ... 21 common frames omittedCaused by: java.lang.ClassNotFoundException: javax.servlet.ServletContext    at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[na:1.8.0_77]    at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[na:1.8.0_77]    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) ~[na:1.8.0_77]    at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_77]    ... 25 common frames omitted

解決方案：添加

        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>javax.servlet-api</artifactId>        </dependency>        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>jstl</artifactId>        </dependency>

刪除其他依賴中的<scope>provided</scope>
