【问题描述】:
我正在使用spring 框架来创建Web 应用程序,并使用maven 作为构建器。
为了与spring 的安全功能进行交互,我在我的pom.xml 中添加了两个不同的依赖项:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>
我命令maven到clean package并执行mvn spring-boot:run得到以下错误信息:
java.lang.IllegalAccessError: 试图从类 org.springframework.boot.bind 访问方法 org.springframework.core.convert.support.DefaultConversionService.addCollectionConverters(Lorg/springframework/core/convert/converter/ConverterRegistry;)V .RelaxedConversionService
从堆栈跟踪中,(添加在下面)我了解到错误以 main 函数开始,该函数位于 Program.java 文件中。main 函数如下:
public static void main(String[] args) {
SpringApplication.run(Program.class, args);
}
注意事项和推测
我的pom.xml 文件是根据我在网上阅读的各种教程编译而成的,一旦我齐心协力,我就继续。
此外,我在 企业网络 后面工作,那里有一个本地存储库,因此某些依赖项可能不是最新的或可用的最新版本。 pom 中某处的版本可能不匹配,但我似乎无法追踪其中一个。
要(尝试)重新创建错误,请复制下面的 pom.xml 并添加 2 个依赖项。
如果无法重新创建,我只能假设其中一个包损坏或损坏(我在本地存储库中遇到过几次坏包)
补充一下,我对maven 和spring 框架还很陌生,请指出您在pom.xml 或结构中看到的任何新手错误。
我的pom.xml 没有两个新的依赖项(运行时工作得很好):
