there seems conflict in your dependencies as you already have spring-boot-starter-web so not required spring-core so remove it and build project again should work.
您的依赖项似乎存在冲突，因为您已经拥有 spring-boot-starter-web，因此不需要 spring-core，因此将其删除并再次构建项目应该可以工作。
remove it
去掉它
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
</dependency>
Have it only web dependency:
只有网络依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
回答by Ken Chan
Because you declare spring-boot-starter-securityin the testscope which means these dependencies is only available during test execution but not available when you run the application normally . Hence FileNotFoundExceptionoccurs when the codes refer to class come from it in the latter case.
因为您spring-boot-starter-security在test范围内声明，这意味着这些依赖项仅在测试执行期间可用，而在您正常运行应用程序时不可用。因此FileNotFoundException，在后一种情况下，当代码引用类时会发生这种情况。
Change it to :
将其更改为：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>

This error occured for me. After putting the mainclassin package it worked for it.
Example:
Previousy it was:
这个错误发生在我身上。放入mainclass包装后，它就起作用了。示例：以前是：
RestAPI.java
RESTAPI.java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class RestAPI
{
public static void main(String[] args) {
SpringApplication.run(RestAPI.class, args);
}
}
After changing it to:
改成后：
RestAPI.java
RESTAPI.java
package restapi;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class RestAPI
{
public static void main(String[] args) {
SpringApplication.run(RestAPI.class, args);
}
}
This worked fine for me.
这对我来说很好。
I am also attaching pom.xmlso that you can check with the versions I was using.
