SpringBoot整合JSP笔记整理

pom添加依赖<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-jasper</artifactId></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><scope>provided</scope></dependency>
</dependencies>
 
springboot build plugin版本1.4.2, 高版本404错误 <plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>1.4.2.RELEASE</version><executions><execution><id>repackage</id><goals><goal>repackage</goal></goals></execution></executions>
</plugin>
 
maven配置jsp资源路径<resources><!-- 打包时将jsp文件拷贝到META-INF目录下--><resource><!-- 指定resources插件处理哪个目录下的资源文件 --><directory>src/main/webapp</directory><!--注意此次必须要放在此目录下才能被访问到--><targetPath>META-INF/resources</targetPath><includes><include>**/**</include></includes></resource>
</resources>
 
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
 
必须使用jdk1.8 （使用17 Unable to open root Jar file 'war:… shiro-web-1.13.0.jar）
webapp/pages/index.jsp<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html lang="en">
<head><title>Home</title>
</head>
<body><h1>欢迎登录， ${user.username}</h1>
</body>
</html>
 
Controller编写@Slf4j
@Controller
public class HelloController {@RequestMapping("/index")public String index(){return "index" ;}
}
