在AEM中，可以使用OSGi配置来定义多字段多值属性。下面是一个示例解决方法：

1. 创建一个OSGi配置类，用于定义属性字段和默认值。例如，创建一个名为MyConfig的类：

package com.example.myproject.config;

import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;

@ObjectClassDefinition(name = "My Configuration", description = "This configuration defines multiple fields and values")
public @interface MyConfig {

    @AttributeDefinition(name = "Field 1", description = "First field")
    String field1() default "";

    @AttributeDefinition(name = "Field 2", description = "Second field")
    String field2() default "";

    @AttributeDefinition(name = "Field 3", description = "Third field")
    String[] field3() default {};

    // Add more fields as needed

}

2. 创建一个OSGi配置实现类，用于访问和设置配置属性。例如，创建一个名为MyConfigImpl的类：

package com.example.myproject.config;

import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Modified;
import org.osgi.service.component.annotations.Activate;
import org.osgi.service.metatype.annotations.Designate;

@Component(service = MyConfigService.class, immediate = true)
@Designate(ocd = MyConfig.class)
public class MyConfigImpl implements MyConfigService {

    private String field1;
    private String field2;
    private String[] field3;

    @Activate
    @Modified
    protected void activate(MyConfig config) {
        field1 = config.field1();
        field2 = config.field2();
        field3 = config.field3();
    }

    @Override
    public String getField1() {
        return field1;
    }

    @Override
    public String getField2() {
        return field2;
    }

    @Override
    public String[] getField3() {
        return field3;
    }

}

3. 创建一个服务接口来访问配置属性。例如，创建一个名为MyConfigService的接口：

package com.example.myproject.config;

public interface MyConfigService {

    String getField1();

    String getField2();

    String[] getField3();

    // Add more getter methods as needed

}

现在，你可以在其他组件中注入MyConfigService接口，并使用它来访问多字段多值属性。例如，在一个Servlet中使用它：

package com.example.myproject.servlet;

import com.example.myproject.config.MyConfigService;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;

import javax.servlet.Servlet;
import javax.servlet.ServletException;
import java.io.IOException;

@Component(service = Servlet.class, property = {
        "sling.servlet.methods=GET",
        "sling.servlet.paths=/bin/myproject/myservlet"
})
public class MyServlet extends SlingAllMethodsServlet {

    @Reference
    private MyConfigService configService;

    @Override
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
        String field1 = configService.getField1();
        String field2 = configService.getField2();
        String[] field3 = configService.getField3();

        // Use the configuration values as needed
        
        response.getWriter().write("Field 1: " + field1 + "\n");
        response.getWriter().write("Field 2: " + field2 + "\n");
        response.getWriter().write("Field 3: " + Arrays.toString(field3) + "\n");
    }

}

以上示例代码演示了如何使用OSGi配置定义和访问多字段多值属性。你可以根据自己的需求，添加更多的字段和值。
