弹簧启动无法识别应用程序.属性文件

您可以尝试在 pom.xml 文件的构建部分中定义资源标记。设置资源目录的路径，其中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：

如果您使用的是spring 3.X版本，则可以添加@PropertySource("application.properties")

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

    // more configuration ...
}

如果您使用 spring 4 版本，则可以使用名为 @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")
})

细节在我的另一个答案中给出：https://stackoverflow.com/a/43659158/2293534

更新#1：

将 App.java 类替换为以下类

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：

使用以下命令

@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。

1. 转到存在 pom.xml 的项目文件夹。

2. 您在pom.xml上有一些错误和警告。我已经澄清了所有内容。

3. 打开命令提示符并运行mvn clean

4. 跑mvn clean install

5. 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。

第一页如下所示http://localhost:8080/

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

[{“id”：1，“userName”：“ychennay”，“reviewText”：“This restaurant was terrific！”}，{“id”：2，“userName”：“david”，“reviewText”：“This restaurant was ok！”}，{“id”：3，“userName”：“ben”，“reviewText”：“This Restaurant was pariccre！”}，{“id”：4，“userName”：“leon”，“reviewText”：“This Restaurant was awful！”}，{“id”：5，“userName”：“Lawrence”，“reviewText”：“这家餐厅令人困惑！”}]

所以替换你的绒球.xml

不要@EnableAutoConfiguration，而应使用如下所示的@Configuration。此外，您将需要修复aws区域属性，因为它在prop文件和代码之间的名称不同 - [amazon.dynamodb.region vs amazon.aws.region] - 一旦它开始拾取属性文件，这将引发错误。

@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;
