java - Dozer org.apache.commons.lang.ClassUtils.getClass(Ljava/lang/String;) 错误

Question

我正在尝试使用 Dozer 映射两个类。但每次我输入映射类的方法时，都会引发以下错误:

org.apache.commons.lang.ClassUtils.getClass(Ljava/lang/String;)

有人知道我错过了什么或做错了什么吗？

我在 src/main/resources 中创建了 dozerBeanMapping.xml 并添加了映射:

 <?xml version="1.0" encoding="UTF-8"?>
    <mappings xmlns="http://dozer.sourceforge.net"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://dozer.sourceforge.net 
http://dozer.sourceforge.net/schema/beanmapping.xsd">
     <mapping>
        <class-a>com.projectx.standard.services.user.model.Address</class-a>
        <class-b>com.projectx.standard.dao.user.model.AddressDTO</class-b>
      </mapping>
    </mappings>

并且还在我的 pom.xml 中添加了以下依赖项:

<dependency>
    <groupId>net.sf.dozer</groupId>
    <artifactId>dozer</artifactId>
    <version>5.3.1</version>
</dependency>
<dependency>
    <groupId>org.apache.xmlbeans</groupId>
    <artifactId>xmlbeans</artifactId>
    <version>2.4.0</version>
    <scope>runtime</scope>
</dependency>

我的类(class)的映射位置是:

public void saveAddress(Address address) {

        Mapper mapperBeanName = DozerBeanMapperSingletonWrapper.getInstance();
        PostalCode postalCode = address.getPostalCode();
        this.postalCodeService.savePostalCode(postalCode);

        address.setFkPostalCode(postalCode.getId());

        AddressDTO addressDTO = mapperBeanName.map(address, AddressDTO.class);
        this.addressServiceDAO.saveAddress(addressDTO);

    }

和堆栈跟踪:

Answer 1

它看起来确实像一个旧的 commons-lang 依赖项。您可以运行:

mvn dependency:tree

查看类路径上是否没有来自该库的其他 jar。如果同一库中有多个 jar(例如在不同版本中)，JVM 可能会使用错误的类。
