Ree*_*ema 7 java jsp spring-mvc maven spring-boot
我正在尝试使用MVC开发一个新的Spring启动应用程序,作为将现有的Spring MVC应用程序移动到Spring启动的第一步.
但是,我遇到了jsp文件映射的问题.
无法解析名为'dispatcherServlet'的servlet中名为'hello'的视图
我已经准备好了很多答案,但似乎没有解决我的问题 - 我不打算使用任何模板引擎,因为我会考虑很多jsps - 一旦设置了spring boot,可能是一个计划.
我有一个项目结构如下:
MyFirstApp
--src/main/java
--uk.co.company
--MainApplication.java
--ServletInitializer.java
--uk.co.company.web
--HelloController.java
--src/main/resources
--static
--templates
--application.properties
--src
--main
--webapp
--WEB-INF
--jsp
--hello.jsp
--pom.xml
放置以下代码:
MyFirstAppApplication.java
@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class,
HibernateJpaAutoConfiguration.class })
@EnableWebMvc
public class MyFirstAppApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(MyFirstAppApplication.class, args);
}
}
ServletInitializer.java
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder
application) {
return application.sources(MyFirstAppApplication.class);
}
}
HelloController.java
@Controller
public class HelloController {
@RequestMapping("/hello")
public String sayHello() {
return "hello";
}
}
为hello.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!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=ISO-8859-1">
<title>Hello</title>
</head>
<body>
hellooo
</body>
</html>
的pom.xml

application.properties
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix:.jsp
我创建了一个渲染jsp的演示项目
Git 网址： https: //github.com/rksharma1401/spring-boot-war
结帐然后 mvn package java -jar target\simple-web-app-tomcat-0.0.1-SNAPSHOT.war URL : http://localhost:8081/w
为什么有两个独立的java类（MyFirstAppApplication，ServletInitializer）扩展SpringBootServletInitializer类？
删除 ServletInitializer.java 并将配置方法从 ServletInitializer 移至 MyFirstAppApplication。
