如何将 BlockHound 添​​加到 Spring Boot 应用程序以检测阻塞调用?

How to add BlockHound to spring boot app to detect blocking calls ?

我没有找到 Spring Boot 应用程序的任何示例:https://github.com/reactor/BlockHound/blob/master/文档/quick_start.md

I didn't find any examples for spring boot apps: https://github.com/reactor/BlockHound/blob/master/docs/quick_start.md

任何帮助将不胜感激.

推荐答案

恕我直言，最明智的选择是在 JUnit 测试执行代码时启用 BlockHound.

IMHO, the wisest choice would be to enable BlockHound while the code is being exercised by JUnit tests.

为此，您只需导入 https://mvnrepository.com/artifact/io.projectreactor.tools/blockhound-junit-platform 与测试范围的依赖关系，它会在您启动 JUnit 测试套件时自动初始化 BlockHound:

To do so you simply need to import the https://mvnrepository.com/artifact/io.projectreactor.tools/blockhound-junit-platform dependency with test scope, which automatically initializes BlockHound when you launch your JUnit tests suite:

<dependency>
  <groupId>io.projectreactor.tools</groupId>
  <artifactId>blockhound-junit-platform</artifactId>
  <version>1.0.0.RC1</version>
  <scope>test</scope>
</dependency>

<小时>

或者，如果您打算一直使用 BlockHound - 而不仅仅是在测试期间 - 您应该导入以下依赖项:

---

Alternatively, if you intend to use BlockHound at all times - and not only during tests - you should instead import the following dependency:

<dependency>
  <groupId>io.projectreactor.tools</groupId>
  <artifactId>blockhound</artifactId>
  <version>1.0.0.RC1</version>
</dependency>

并在您的主方法中调用 BlockHound.install()，就在引导您的 Spring Boot 应用程序之前:

And call BlockHound.install() in your main method, just before bootstrapping your Spring Boot application:

@SpringBootApplication
public class BlockhoundDemoApplication {

    public static void main(String[] args) {
        BlockHound.install();

        SpringApplication.run(BlockhoundDemoApplication.class, args);
    }

}
