Java8上的命名参数

Question

UPD：最后，此功能可以通过命令行运行项目，而不能从IntellijIdea运行。 如何强制intellijidea中的Junit与-parameters标志一起使用？

我有一个使用Spring Data JPA和Hibernate的Java应用程序。 我正在使用Java8运行它，这是我的示例CrudRepository：

public interface CRepository extends CrudRepository<C, Integer> {
@Transactional(readOnly = true)
@Query("select sum(cnt.went-cnt.left) from C cnt " +
        "where cnt.shop = :shop " +
        "and cnt.time between :startDate and :endDate")
int sumBetweenDatesByShop(Shop shop, Timestamp startDate, Timestamp endDate);
}

当我运行单元测试以检查其是否正常运行时，出现了这样的异常：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Name for parameter binding must not be null or empty! For named parameters you need to use @Param for query method parameters on Java versions < 8.; nested exception is java.lang.IllegalArgumentException: Name for parameter binding must not be null or empty! For named parameters you need to use @Param for query method parameters on Java versions < 8.

如果我的spring-boot应用程序在仅安装Java = Java8的PC上编译，打包和运行，为什么会得到它。

感谢您的时间和帮助。

如果我将尝试在查询中调用诸如'？1'之类的参数，或者使用@Param（）注释对参数进行注释，则可以正常工作，但我想知道为什么它现在无法正常工作。

看起来答案是在编译器中添加-parameters标志，但是我不知道如何为spring-boot应用程序添加此标志，我试图这样添加它，但是我认为maven编译器插件未在spring-boot中使用应用程序编译（可能是由于intellijidea？）：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
             <compilerArgs>
                  <arg>-parameters</arg>
             </compilerArgs>
    </configuration>
</plugin>

Answer 1

假设您在pom中具有以下配置：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
             <compilerArgs>
                  <arg>-parameters</arg>
             </compilerArgs>
    </configuration>
</plugin>

在Intellij中，转到“运行/调试配置”，找到用于运行单元测试的配置（或为要受影响的项目/类创建一个新配置），在botton的“启动前”部分中其中一项：

• 使

通过选择该项目并单击-按钮将其删除。 然后使用+按钮添加新的“运行Maven目标”项目。 在添加对话框中，选择Pom所在的适当目录。 并在命令行中键入“ test-compile”。 从Intellij或命令行运行“ mvn clean”。 做完了
