Question

我无法让Orika使用eclipse工作....我添加了maven orika依赖项（1.4.6）并且我创建了一个样本junit测试

import java.util.List;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;
import ma.glasnost.orika.MapperFacade;
import ma.glasnost.orika.MapperFactory;
import ma.glasnost.orika.impl.DefaultMapperFactory;

public class OrikaTest {

    @Test
    public void test() {
        //System.setProperty(OrikaSystemProperties.COMPILER_STRATEGY,EclipseJdtCompilerStrategy.class.getName());

        MapperFactory mapperFactory = new DefaultMapperFactory.Builder()
                .build();

        mapperFactory
            .classMap(PersonDTO.class, PersonEntity.class)
            .field("cellPhone", "phone")
            .byDefault()
            .register();

        PersonDTO dto = new PersonDTO();
        dto.setFirstName("John");
        dto.setLastName("Smith");
        //dto.setRoles(Lists.newArrayList("Role1", "Role2"));
        dto.setCellPhone("845-111-2222");

        MapperFacade mapper = mapperFactory.getMapperFacade();

        PersonEntity entity = mapper.map(dto, PersonEntity.class);

        assertEquals(entity.getFirstName(), "Jeff");
        assertNotNull("Roles not filled", entity);

    }

}

class PersonDTO {
    private String firstName;
    private String lastName;
    private String cellPhone;
    private List<String> roles;

    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public List<String> getRoles() {
        return roles;
    }
    public void setRoles(List<String> roles) {
        this.roles = roles;
    }
    public String getCellPhone() {
        return cellPhone;
    }
    public void setCellPhone(String cellPhone) {
        this.cellPhone = cellPhone;
    }
}

class PersonEntity {
    private String firstName;
    private String lastName;
    private String phone;
    private List<String> roles;

    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public List<String> getRoles() {
        return roles;
    }
    public void setRoles(List<String> roles) {
        this.roles = roles;
    }
}

当我运行单元测试时，我得到以下异常：

ma.glasnost.orika.MappingException：ma.glasnost.orika.impl.generator.CompilerStrategy $ SourceCodeGenerationException：类PersonDTO无法访问在ma.glasnost.orika.impl.generator.MapperGenerator.build（MapperGenerator.java:105） at ma.glasnost.orika.impl.DefaultMapperFactory.buildMapper（DefaultMapperFactory.java:1372） at ma.glasnost.orika.impl.DefaultMapperFactory.build（DefaultMapperFactory.java:1199） at ma.glasnost.orika.impl.DefaultMapperFactory.getMapperFacade（DefaultMapperFactory.java:859）在OrikaTest.test（OrikaTest.java:37） at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method） at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:57） at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43） at java.lang.reflect.Method.invoke（Method.java:606）在org.junit.runners.model.FrameworkMethod $ 1.runReflectiveCall（FrameworkMethod.java:47）在org.junit.internal.runners.model.ReflectiveCallable.run（ReflectiveCallable.java:12）在org.junit.runners.model.FrameworkMethod.invokeExplosively（FrameworkMethod.java:44）在org.junit.internal.runners.statements.InvokeMethod.evaluate（InvokeMethod.java:17）在org.junit.runners.ParentRunner.runLeaf（ParentRunner.java:271）在org.junit.runners.BlockJUnit4ClassRunner.runChild（BlockJUnit4ClassRunner.java:70）在org.junit.runners.BlockJUnit4ClassRunner.runChild（BlockJUnit4ClassRunner.java:50）在org.junit.runners.ParentRunner $ 3.run（ParentRunner.java:238）在org.junit.runners.ParentRunner $ 1.schedule（ParentRunner.java:63）在org.junit.runners.ParentRunner.runChildren（ParentRunner.java:236）在org.junit.runners.ParentRunner.access $ 000（ParentRunner.java:53）在org.junit.runners.ParentRunner $ 2.evaluate（ParentRunner.java:229）在org.junit.runners.ParentRunner.run（ParentRunner.java:309）在org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run（JUnit4TestReference.java:86）在org.eclipse.jdt.internal.junit.runner.TestExecution.run（TestExecution.java:38）在org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests（RemoteTestRunner.java:459）在org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests（RemoteTestRunner.java:675）在org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run（RemoteTestRunner.java:382）在org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main（RemoteTestRunner.java:192）引起：ma.glasnost.orika.impl.generator.CompilerStrategy $ SourceCodeGenerationException：类PersonDTO无法访问在ma.glasnost.orika.impl.generator.JavassistCompilerStrategy.assureTypeIsAccessible（JavassistCompilerStrategy.java:155）在ma.glasnost.orika.impl.generator.MapperGenerator.build（MapperGenerator.java:58） ......还有27个

注意：我在控制台中看到eclipse打印定义的映射。但是，执行时出现上述错误：

MapperFacade mapper = mapperFactory.getMapperFacade();

如果我尝试使用EclipseJdtCompilerStrategy，通过设置系统属性，我得到一个不同的例外：

非常感谢任何帮助

关于

class PersonDTO is not accessible at
    ma.glasnost.orika.impl.generator.JavassistCompilerStrategy.assureTypeIsAccessible(JavassistCompilerStrategy.java:155)

您的PersonDTO类是包可见的，因此Orika代码无法从其包中访问它。将其设为public class，该问题应该消失。供参考，请参阅Orika代码中的that line。

当您使用默认（Javassist）编译器时会发生这种情况。

对于Eclipse编译器，请仔细检查您是否添加了相关的Maven依赖项

<dependency>
   <groupId>ma.glasnost.orika</groupId>
   <artifactId>orika-eclipse-tools</artifactId>
   <version>1.4.6</version><!-- should correspond to your core Orika version -->
</dependency>

并在创建mapperFactory时启用编译器

MapperFactory factory = 
    new DefaultMapperFactory.Builder()
            .compilerStrategy(new EclipseJdtCompilerStrategy())
            .build();

系统属性应该用作后备，所以请使用上面的构建器方法。

有关详细信息，请参阅Troubleshooting Guide“启用步骤调试”部分。
