添加 Springs LDAP-Core 后终止

如何解决添加 Springs LDAP-Core 后终止

我使用 Spring Boot 构建了一个简单的应用程序。

Test.java

package Test;

import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.scheduling.annotation.*;

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

我尝试为 LDAP 添加依赖项。

<dependency>
        <groupId>org.springframework.ldap</groupId>
        <artifactId>spring-ldap-core</artifactId>
        <version>2.3.3.RELEASE</version>
    </dependency>

然后它立即终止。

有什么办法让它正常启动吗？

解决方法

我怀疑你有版本号冲突。

在创建 Spring Boot 项目时，我建议您使用 spring boot initializer。您可以在此处选择所需的依赖项。然后他们为你生成一个项目，当你查看 pom 时，你会看到在顶部声明了一个父 pom。

通常看起来像这样，并且包含该 Spring Boot 版本的版本：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.4.2</version>
</parent>

这个 parent 是必不可少的，因为 spring boot 是一个框架，所以框架的每个版本都包含具有特定版本号的依赖项。父 pom 确保所有依赖项都是协同工作的版本号。您可以阅读 Spring 中的 Java 项目如何设置 here。

这也意味着在声明其他 spring 依赖项时可以省略版本号，因为父 pom 将选择一个适用于该版本 spring boot 的版本号。

// no need for version numbering it gets fetched from the parent
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

所以当你声明 ldap 依赖时你也可以省略版本号。

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-ldap</artifactId>
</dependency>

但是正如上面提到的，使用初始化器创建一个spring boot项目。超级简单。
