Spring Boot无法识别application.properties文件

  您可以尝试在pom.xml文件的build部分中定义resources标记 . 设置资源目录的路径 application.properties

  <build>
          <resources>
              <resource>
                  <directory>resources</directory>
                  <targetPath>${project.build.outputDirectory}</targetPath>
                  <includes>
                      <include>application.properties</include>
                  </includes>
              </resource>
          </resources>
  </build>

  另一种方法：

  如果你使用spring 3.X版本，你可以添加 @PropertySource("application.properties")

  @Configuration
  @PropertySource(value = "classpath:application.properties")
  public class ApplicationConfig {
  
      // more configuration ...
  }
  

  如果使用spring 4版本，则使用名为@PropertySources的新注释添加2个属性文件，该注释允许您声明重复的@PropertySource注释：

  @PropertySources({
      @PropertySource("default.properties"),
      @PropertySource("overriding.properties")
  })

  更新＃1：

  用以下类替换App.java类

  import org.springframework.boot.SpringApplication;
  import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
  import org.springframework.boot.autoconfigure.SpringBootApplication;
  import org.springframework.boot.builder.SpringApplicationBuilder;
  import org.springframework.boot.context.web.SpringBootServletInitializer;
  import org.springframework.context.annotation.ComponentScan;
  import org.springframework.context.annotation.Configuration;
  
  //@SpringBootApplication
  @Configuration
  @ComponentScan
  @EnableAutoConfiguration
  public class Application extends SpringBootServletInitializer {
  
      public static void main(String[] args) {
          SpringApplication.run(Application.class, args);
      }
  
  
      @Override
      protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
          return application.sources(applicationClass);
      }
  
      private static Class<Application> applicationClass = Application.class;
  }
  

  对于java.io.FileNotFoundException：

  使用以下内容

  @PropertySource(value = "database.properties", ignoreResourceNotFound = true)
  

  更新＃2：

  我已按照以下步骤运行您的应用程序 . 它运行成功 .

  • 转到存在pom.xml的项目文件夹 .

  • 你在pom.xml上有一些错误和警告 . 我澄清了一切 .

  • 打开命令提示符并运行 mvn clean

  • 运行 mvn clean install

  • 最后 mvn spring-boot:run

  然后在浏览器中，我运行“http://localhost:8080/”

  它成功打开了项目 . 我也搜索过其他页面也成功打开了 .

  首页如下所示 http://localhost:8080/
  

  查看所有页面如下所示： http://localhost:8080/api/reviews

  [{“id”：1，“userName”：“ychennay”，“reviewText”：“这家餐厅太棒了！”}，{“id”：2，“userName”：“david”，“reviewText”：“这家餐厅还可以！“}，{”id“：3，”userName“：”ben“，”reviewText“：”这家餐厅很平庸！“}，{”id“：4，”userName“：”leon“ ，“reviewText”：“这家餐厅很糟糕！”}，{“id”：5，“userName”：“lawrence”，“reviewText”：“这家餐馆很混乱！”}]

  所以替换你的pom.xml

  而不是@EnableAutoConfiguration，使用@Configuration，如下所示 . 此外，您将需要修复aws region属性，因为它在prop文件和代码之间的名称不同 - [amazon.dynamodb.region vs amazon.aws.region] - 一旦它在下面的更改后开始拾取属性文件，这将抛出错误 .

  @Configuration
  @PropertySource("database.properties")
  public class DynamoClientMapper {
  
      @Value("${amazon.dynamodb.endpoint}")
      private String amazonDynamoDBEndpoint;
  
      @Value("${amazon.aws.accesskey}")
      private String amazonAWSAccessKey;
  
      @Value("${amazon.aws.secretkey}")
      private String amazonAWSSecretKey;
  
      @Value("${amazon.aws.region}")
      private String amazonAWSRegion;

  尝试了以下方法？

  @Component
  @PropertySource("database.properties")
  public class DynamoClientMapper { ...}
  

  要么

  @Service
   @PropertySource("database.properties")
   public class DynamoClientMapper { ...}
