SpringBoot整合JSP笔记整理

1. pom添加依赖

   <dependencies>
       <dependency>
           <groupId>org.springframework.bootgroupId>
           <artifactId>spring-boot-starter-webartifactId>
       dependency>
       <dependency>
           <groupId>org.apache.tomcat.embedgroupId>
           <artifactId>tomcat-embed-jasperartifactId>
       dependency>
       <dependency>
           <groupId>javax.servletgroupId>
           <artifactId>jstlartifactId>
       dependency>
       <dependency>
           <groupId>javax.servletgroupId>
           <artifactId>javax.servlet-apiartifactId>
           <scope>providedscope>
       dependency>
   dependencies>
   

2. springboot build plugin版本1.4.2, 高版本404错误

    <plugin>
       <groupId>org.springframework.bootgroupId>
       <artifactId>spring-boot-maven-pluginartifactId>
       <version>1.4.2.RELEASEversion>
       <executions>
           <execution>
               <id>repackageid>
               <goals>
                   <goal>repackagegoal>
               goals>
           execution>
       executions>
   plugin>
   

3. maven配置jsp资源路径

   <resources>
       
       <resource>
           
           <directory>src/main/webappdirectory>
           
           <targetPath>META-INF/resourcestargetPath>
           <includes>
               <include>**/**include>
           includes>
       resource>
   resources>
   

4. application中添加配置

   ## 这里目录是以webapp为根目录的相对路径配置
   spring.mvc.view.prefix=/pages/
   spring.mvc.view.suffix=.jsp
   

5. 必须使用jdk1.8 （使用17 Unable to open root Jar file 'war:… shiro-web-1.13.0.jar）
6. webapp/pages/index.jsp

   <%@ page contentType="text/html;charset=UTF-8" language="java" %>
   
   
       
   
   
       
   欢迎登录， ${user.username}
   
   
   

7. Controller编写

   @Slf4j
   @Controller
   public class HelloController {
       @RequestMapping("/index")
       public String index(){
           return "index" ;
       }
   }
