Spring boot 404 error Not found error in multi module project

Question

我正在嘗試運行我的第一個 spring 引導多模塊項目。

通過從 postman http://localhost:8080/test 調用我得到 404 狀態

這是我的引導 POM.XML

 <?xml version="1.0" encoding="UTF-8"?> <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/xsd/maven-.0.0.xsd"> <parent> <artifactId>gestionactive</artifactId> <groupId>com.entreprise</groupId> <version>0.0.1-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>bootstrap</artifactId> <packaging>jar</packaging> <properties> <maven.compiler.source>8</maven.compiler.source> <maven.compiler.target>8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>com.entreprise</groupId> <artifactId>infrastructure</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> </project>

這是我在引導模塊中的主要 class ：

package restapi;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class UserA {

    @GetMapping("/test")
    public String getTest(){
        return "TEST";
    }

}

我的 REST CONTROLLER（在基礎設施模塊中）

 package restapi; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class UserA { @GetMapping("/test") public String getTest(){ return "TEST"; } }

我不知道如何管理模塊依賴項以使此代碼正常工作

預先感謝！

Answer 1

我有這個錯誤並面臨創建兩個配置文件。 controller 向 spring 說明其中 package 尋找

@Configuration
@ComponentScan
public class InfrastructureConfig {
}

還有一個讓應用程序告訴應用程序您的模塊的規則，因為您只有一個，您將擁有類似的 InfrastructureConfig

@Configuration
@Import({
        InfrastructureConfig.class,
})
public class BootstrapConfig {
}

將這兩個文件放在各自的模塊中。
