Question

我得到SpringBootServletInitializer cannot be resolved to a type 据我所知，这是一个依赖问题。

虽然我觉得编写Java代码很舒服，但这是我使用maven和spring-boot的第一个应用程序，我自然也很无能为力。

的pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </plugins>
    </build>

</project>

SpringBootApplication.java：

package com.thebyteguru.launcher;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;

public class SpringBootApplication extends SpringBootServletInitializer {

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootApplication.class);
    }

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

}

我可以看到相关的jar文件存在于Maven Dependencies文件夹中，而import文件存在于所需的class＆＃39;我注意到package已经存在，但它们是＃34;空的＆＃34;（意思是intellisense找到包但不包含其中的类）。

我缺少什么？

Answer 1

我遇到了同样的问题。我的解决方案是

而不是

import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

使用

import org.springframework.boot.web.support.SpringBootServletInitializer;

也在pom

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.6.RELEASE</version>
</parent>

Answer 2

不要做任何新事只需在你的eclipse中按 Ctrl + Shift + o 它会为你的项目添加正确的导入

Answer 3

我遇到了同样的问题...但是我在Spring Boot 2.1.1中使用了Maven。

所以我需要指定正确的父级... AND 更改导入/类名称：

pom.xml：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.1.RELEASE</version>
</parent>

MyApp.java：

...
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
// import org.springframework.boot.web.support.SpringBootServletInitializer;  // OBSOLETE
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringBootWebApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootWebApplication.class);
    }

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

Answer 4

我正在遵循相同的课程，我只是设置了这样的pom：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.6.RELEASE</version>
</parent>

工作正常

依赖性问题＆＃34; SpringBootServletInitializer无法解析为类型＆＃34;
