Question

我正在尝试使用SpringMVC使用JSP和SpringBoot创建UI。正确完成所有配置后，我仍然收到错误-“ java.lang.ClassNotFoundException：org.eclipse.jdt.internal.compiler.env.INameEnvironment”，我已经做了很多尝试来解决它，但是仍然无法正常工作。如果有人可以帮助我。预先谢谢你。

我的SpringBoot页面

    package com.capgemini.PACE.PACE;

    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;

    @Controller
    public class HelloController {

@RequestMapping("/")
public String Hello()
{
    return "/Hello";
}
    }

我的pom.xml

    package com.capgemini.PACE.PACE;

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;

    @SpringBootApplication
    public class PaceApplication {

public static void main(String[] args) {
    SpringApplication.run(PaceApplication.class, args);
}

    }

我的JSP页面

    <body>
    <h1>HEllo!!</h1>

我试图在pom.xml中添加这些依赖项仍然无法正常工作

    server.port=8082
    spring.mvc.view.prefix = /WEB-INF/views/
    spring.mvc.view.suffix = .jsp
    spring.mvc.static-path-pattern=/resources/**

我遇到错误-

    <dependency>
        <groupId>javax.servlet.jsp.jstl</groupId>
        <artifactId>javax.servlet.jsp.jstl-api</artifactId>
        <version>1.2.1</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.1</version>

In my case it worked by adding this dependency in pom.xml file.
It is needed to compile jsp don't know why tomcat-embed-jasper version is not working
        <dependency>
            <groupId>org.eclipse.jdt.core.compiler</groupId>
            <artifactId>ecj</artifactId>
            <version>4.6.1</version>
            <scope>provided</scope>
        </dependency>
