Question

我有一个带有一个测试类 DbTest 的Maven模块。运行测试时，不会拾取属性文件application.properties。线 DvsTestDbConfig 中的 System.out.println 显示{database.test}而不是qqqqqqqqq（当前的虚拟值）。知道为什么spring找不到属性文件吗？

DbTest

package ch.admin.estv.dvs.test.database;

import ch.admin.estv.dvs.test.database.config.DvsTestDbConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.context.annotation.Import;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@Import(DvsTestDbConfig.class)
public class DbTest {

    @Test
    public void givenPartnerToDelete_whenPartnerDelete_thenNoEntryExist() {

        System.out.println("test started");
    }
}

DvsTestDbConfig

package ch.admin.estv.dvs.test.database.config;

Answer 1

用@SpringBootTest注释测试类。更多详细信息和替代方法：Populating Spring @Value during Unit Test

Answer 2

添加

<androidx.appcompat.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="70dp"
    android:background="@android:color/holo_blue_light"
    android:elevation="4dp"
    android:paddingTop="7dp"
    app:layout_scrollFlags="scroll|enterAlways"
    app:titleTextColor="@android:color/white">

    <TextView
        android:id="@+id/toolbar_title"
        android:layout_width="wrap_content"
        android:layout_height="?attr/actionBarSize"
        android:layout_gravity="center_horizontal|top"

注释

通过环境解析的属性位于一个或多个中   “属性源”对象和@Configuration类可能会有所贡献   属性资源使用@PropertySource传递给Environment对象   注释：
