I created a project with spring boot 2.1.1 and when I try to lift it I get the following error:
我用 spring boot 2.1.1 创建了一个项目，当我尝试解除它时，出现以下错误：

I think this dependency:
我认为这种依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
Made a conflict with this one:
与此发生冲突：
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<type>jar</type>
</dependency>
Why do you need the last one? I think you don't need it, because you already has starter for security, so remove it.
为什么需要最后一个？我认为你不需要它，因为你已经有了安全启动器，所以删除它。
回答by hongming.wu
I encountered the same problem today. It turns out the problem was caused by the main startup class not being placed at the outermost level of the code. Make sure that you have defined the startup class at the correct location.
我今天遇到了同样的问题。事实证明，问题是由主启动类未放置在代码的最外层引起的。确保您在正确的位置定义了启动类。
回答by Matthew Buckett
The error is helpful in that it can't find the required class javax.servlet.Filterand a common way to have this class is through this dependency:
该错误很有用，因为它找不到所需的类javax.servlet.Filter，而拥有此类的常用方法是通过此依赖项：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
which ends up pulling in org.apache.tomcat.embed:tomcat-embed-core
最终拉入 org.apache.tomcat.embed:tomcat-embed-core
We were seeing this locally because when running the Spring Boot application from Intellij we didn't have the option 'Include dependencies with "Provided" scope' in the Run/Debug Configuration ticked.
我们在本地看到了这一点，因为当从 Intellij 运行 Spring Boot 应用程序时，我们没有在运行/调试配置中勾选“包含具有“提供”范围的依赖项选项。

Try adding this to your pom.xml:
尝试将其添加到您的 pom.xml 中：
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>

It helped me.
