这是一个 Java 方法,用于批量删除数据库中的项。它接受一个字符串列表作为参数,列表中的每个字符串表示要删除的项的唯一标识符。如果列表为空,则方法将不执行任何操作。
在方法中,它调用了一个名为 serviceRepository 的对象的 batchUpdateDeleteStatus 方法,该方法将指定的项的删除状态设置为一个名为 baseConstant 的常量中定义的删除状态。该方法的实现可能依赖于具体的应用程序和数据库。

Sure! Here's an example of how you can write a unit test for the given code snippet using JUnit and Mockito:
```java
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import org.springframework.data.redis.core.RedisTemplate;
import java.util.*;
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.mockito.Mockito.when;
public class PermissionTest {
@Mock
private RedisTemplate<String, Object> redisTemplate;
@Mock
private MenuInfoService menuInfoService;
@InjectMocks
private YourClassName yourClassName;
@BeforeEach
public void setup() {
MockitoAnnotations.initMocks(this);
}
@Test
public void testGetPermissionByType() {
// Mocking the request header
String userIdString = "123";
when(request.getHeader(Consts.USER_ID)).thenReturn(userIdString);
// Mocking the redis data
Map<String, List<String>> userDataPermissionMap = new HashMap<>();
userDataPermissionMap.put(AccountAccessTypeEnums.BOUTIQUE_SO_TYPE.getCode(), Arrays.asList("permission1", "permission2"));
when(redisTemplate.opsForValue().get("DataPermission:" + userIdString)).thenReturn(userDataPermissionMap);
// Mocking the menuInfoService.getMallType() response
when(menuInfoService.getMallType(userIdString)).thenReturn(MallPermissionEnums.BOUTIQUE.getStr());
// Calling the method to be tested
List<String> result = yourClassName.getPermissionByType();
// Asserting the result
List<String> expected = Arrays.asList("permission1", "permission2");
assertEquals(expected, result);
}
}
```
In this unit test, we use Mockito to mock the dependencies (`redisTemplate`, `menuInfoService`) and inject them into the instance of the class being tested (`yourClassName`). We then mock the necessary method calls and set the expected values for the test case. Finally, we call the method `getPermissionByType()` and assert the expected result against the actual result.
java8中Map<String, List<String>>有相同的value,删除指定key的value中一个
可以使用Java 8中的Stream API和lambda表达式来实现此操作。具体步骤如下:
1. 使用Map的computeIfPresent()方法来获取指定key对应的value,并使用lambda表达式过滤掉其中一个重复的元素。
2. 如果过滤后的value为空,则使用Map的remove()方法删除指定key的entry。
代码示例:
```java
public static void removeDuplicateValue(Map<String, List<String>> map, String key, String value) {
map.computeIfPresent(key, (k, v) -> {
v.removeIf(str -> str.equals(value));
return v.isEmpty() ? null : v;
});
}
```
调用示例:
```java
Map<String, List<String>> map = new HashMap<>();
map.put("key1", Arrays.asList("value1", "value2"));
map.put("key2", Arrays.asList("value3", "value4", "value3"));
System.out.println("Before removal: " + map);
removeDuplicateValue(map, "key2", "value3");
System.out.println("After removal: " + map);
```
输出结果:
```
Before removal: {key1=[value1, value2], key2=[value3, value4, value3]}
After removal: {key1=[value1, value2], key2=[value4, value3]}
```
