dropwizard 中的 Guice 依赖注入不起作用 - 它是 pom.xml 工件依赖问题吗？

Question

我想要运行 Dropwizard（REST 应用程序）。

我有一个 pom.xml 文件，它使用旧版本的 dropwizard (1.0.3)，它可以工作。对于新版本 (2.0.10)，还有另一个 pom.xml 可用，但它没有运行。

这是可用的 pom.xml（DropWizard 的 1.0.3 版本），可在 githut 上找到：

https://github.com/userInterview/dropwizard-guice

只需复制过去 pom.xml 即可重现错误或工作版本。

这是两个 pom.xml 文件：

这是适用于旧版 DropWizard 版本 (1.03) 的对应 pom.xml

最后，如果我使用另一种神器，即现代神器：5.2.0 版中的“dropwizard-guicey”，服务器将正常启动

注意：enpoint“/brands/name”不起作用！这是因为注入问题。（注意！）

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <mainclass>com.dropwizard.application.MainApplication</mainclass>
</properties>

<dependencies>
    <dependency>
        <groupId>ru.vyarus</groupId>
        <artifactId>dropwizard-guicey</artifactId>
        <version>5.2.0</version>
    </dependency>
</dependencies>

dropwizard 中的 Guice 依赖注入不起作用 - 它是 pom.xml 工件依赖问题吗？

Guice Dependency Injection in dropwizard not working - is it a pom.xml artifacts dependency problem?

java

rest

dependency-injection

dropwizard

dropwizard-guice
