说properties运行JAR最佳的人在执行中使用的文件属于其中是否正确META-INF？这个概念是正好与标准的目录结构指定的Maven。

假设需要这种结构，如何properties从中加载文件META-INF？

我无法从嵌入的文档中检索地址字段。我还没有看到 3.4 MongoDB 驱动程序的任何解决方案。

System.out.println("Selecting Person ");

MongoCollection<Document> collection = mdb.getCollection("Person");
MongoCursor<Document> cursor = collection.find().iterator();

try {           
    while (cursor.hasNext()) {
        Document temp_person_doc=cursor.next();
        Document temp_address_doc=temp_person_doc.get("address");   
        String houseNo=temp_address_doc.getString("houseNo");       
    }
} finally {
    cursor.close();
}   

这是文档结构。

{
    "_id" : "5aae9920982f271ba4b08735",
    "firstName" : "homer",
    "surname" : "simpson",
    "address" : {
        "houseNo" : 742,
        "address" : "evergreen terrace",
        "city" : "springfield",
    }
}

我想测试我的控制器，并使用以下方法对其进行测试：

package spittr.web;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.view;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.standaloneSetup;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import org.junit.Test;
import org.mockito.Mockito;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.web.servlet.view.InternalResourceView;

import spittr.data.Spittle;
import spittr.data.SpittleRepository;

public class SpittleControllerTest {
    @Test
    public void shouldShowRecentSpittles() throws Exception {
        List<Spittle> expectedSpittles = createSpittleList(20);
        SpittleRepository mockRepository = Mockito.mock(SpittleRepository.class);

        Mockito.when(mockRepository.findSpittles(Long.MAX_VALUE, 20))
            .thenReturn(expectedSpittles);

        SpittleController controller = new SpittleController(mockRepository);

        MockMvc mockMvc = standaloneSetup(controller)
            .setSingleView(
                new InternalResourceView("/WEB-INF/views/spittles.jsp"))
            .build();

        mockMvc.perform(get("/spittles"))
            .andExpect(view().name("spittles"))
            .andExpect(model().attributeExists("spittleList"))
            .andExpect(model().attribute("spittleList", hasItems(expectedSpittles.toArray())));
    }

    private List<Spittle> createSpittleList(int count) {
        List<Spittle> spittles = new …

我有一个包含多个模块的项目。每个模块都有自己的logback.xml。他们的附加程序是滚动文件。如何在每个输出日志文件的开头添加特定的表达式？

如果我org.junit.Test在运行 JUnit 时导入，它会给我一个错误，如“未找到 Test Runner JUnit 5 的测试”。

相反，如果我导入，org.junit.jupiter.api.Test那么我可以运行 JUnit 测试。
