如何在Spring MVC中解析JpaRepository<>

根据您提供的信息,我能提供的唯一帮助如下:

你可以直接跳到下面的段落 Jar List 看看你是否有以下文件?

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    </properties>

        </dependency>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

获取所有依赖项jar

mvn dependency:copy-dependencies -DoutputDirectory=target/libs

\- jakarta.persistence:jakarta.persistence-api:jar:3.2.0:compile

建议:

(1) 您创建了一个空目录,

(2) 然后生成pom.xml(如上所述),

(3) 然后执行 mvn dependency:copy-dependencies -DoutputDirectory=target/libs 命令

(4) 可以在中获取所有依赖的jar文件 target/libs 目录,然后将其复制到您的webapp项目中。
