本文介绍了SpringBoot集成jsp（附源码）+遇到的坑 ，分享给大家
1、大体步骤
（1）创建Maven web project；
（2）在pom.xml文件添加依赖；
（3）配置application.properties支持jsp
（4）编写测试Controller
（5）编写JSP页面
（6）编写启动类App.java
2、新建SpringInitialzr
3、pom文件
<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文件
# 页面默认前缀目录 spring.mvc.view.prefix=https://www.jb51.net/WEB-INF/jsp/ # 响应页面默认后缀 spring.mvc.view.suffix=.jsp # 自定义属性，可以在Controller中读取 application.hello=Hello GOD
5、Controller文件
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. */ @Controller public class HelloController { // 从 application.properties 中读取配置，如取不到默认值为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页面
<%@ 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、遇到的问题
1、Spring Boot: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean
把pom中所有的<scope>provided</scope>注释掉
2、报404
<1>注意controller和restcontroller区别
<2>检查application.properties
<3>检查pom是否缺支持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
解决方案：添加以下依赖
<dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> </dependency>
4、java.lang.NoClassDefFoundError: javax/servlet/ServletContext
