按包名称扫描resteasy资源 [英] scan resteasy resources by package name

问题描述

我正在配置我的resteasy应用程序，需要开启自动扫描（两个jaxrs应用程序在类路径，它在加载时断开）

因此，已配置我的web.xml如下：

 < context-param& 
< param-name> resteasy.scan< / param-name> 
< param-value> false< / param-value> 
< / context-param> 
 
< context-param> 
< param-name> resteasy.resources< / param-name> 
< param-value> 
 io.swagger.jaxrs.listing.ApiListingResource，
 com.mycompany.resource.ClientResource，
 com.mycompany.resource.AccountResource，
 ... etc 
 < / param-value> 
< / context-param> 
  

在resteasy中有任何方法可以扫描包（ com.mycompany。资源。* ）名称，而不必添加每个资源？

解决方案

文档很清楚：

要注册的完全限定的JAX-RS资源类名称的逗号分隔列表

您可以自行实现此功能，例如反射库。假设以下文本文件：

  com.foo.bar.TestResource 
 com.foo.baz。* 
我们可以在Application类中读取这个文本文件，搜索所有类，并将它添加到<$ c返回的集合中  getClasses ：
  @ApplicationPath（/）
 public class RestApplication extends应用程序{
 
 Set< Class<？>>类; 
 
 public RestApplication（@Context ServletContext servletContext）{
 classes = new HashSet<>（）; 
 try {
 URI resourcesConfig = servletContext.getResource（/ WEB-INF / resources.txt）。toURI（）; 
 List< String> resources = Files.readAllLines（Paths.get（resourcesConfig），Charset.forName（UTF-8））; 
 for（String resource：resources）{
 parseResources（resource）; 
} 
} catch（IOException | URISyntaxException | ClassNotFoundException ex）{
 throw new IllegalArgumentException（Could not add resource classes，ex）; 
} 
} 
 
 private void parseResources（String resource）throws ClassNotFoundException，IOException {
 if（！resource.endsWith（。*））{
 classes.add（Class.forName（resource））; 
 return; 
} 
 String pkg = resource.substring（0，resource.length（） -  2）; 
反射反射=新反射（pkg）; 
 for（Class<？> scannedResource：reflections.getTypesAnnotatedWith（Path.class））{
 classes.add（scannedResource）; 
} 
} 
 
 @Override 
 public Set< Class<？>> getClasses（）{
 return classes; 
} 
 
} 
  
注意：资源在类级别上具有 @Path 注释。
 
I'm configuring my resteasy app and need to turn of auto scanning (two jaxrs applications are in the classpath and it breaks at loading)

For that reason I have configured my web.xml as follow:
    <context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>false</param-value>
</context-param>

<context-param>
    <param-name>resteasy.resources</param-name>
    <param-value>
        io.swagger.jaxrs.listing.ApiListingResource,
        com.mycompany.resource.ClientResource,
        com.mycompany.resource.AccountResource,
        ... etc
    </param-value>
</context-param>
Is there any way in resteasy to scan by package (com.mycompany.resource.*) name instead of having to add each resource ? It seems it's possible with jaxrs but not resteasy
解决方案
The documentation is quite clear:

  
A comma delimited list of fully qualified JAX-RS resource class names you want to register
You could implement this on your own using for instance the reflections library. Assuming following textfile:
com.foo.bar.TestResource
com.foo.baz.*
We can read this textfile in the Application class, search for all classes and add it to the Set returned by getClasses:
@ApplicationPath("/")
public class RestApplication extends Application {

    Set<Class<?>> classes;

    public RestApplication(@Context ServletContext servletContext) {
        classes = new HashSet<>();
        try {
            URI resourcesConfig = servletContext.getResource("/WEB-INF/resources.txt").toURI();
            List<String> resources = Files.readAllLines(Paths.get(resourcesConfig), Charset.forName("UTF-8"));
            for (String resource : resources) {
                parseResources(resource);
            }
        } catch (IOException | URISyntaxException | ClassNotFoundException ex) {
            throw new IllegalArgumentException("Could not add resource classes", ex);
        }
    }

    private void parseResources(String resource) throws ClassNotFoundException, IOException {
        if (!resource.endsWith(".*")) {
            classes.add(Class.forName(resource));
            return;
        }
        String pkg = resource.substring(0, resource.length() - 2);
        Reflections reflections = new Reflections(pkg);
        for (Class<?> scannedResource : reflections.getTypesAnnotatedWith(Path.class)) {
            classes.add(scannedResource);
        }
    }

    @Override
    public Set<Class<?>> getClasses() {
        return classes;
    }

}
NOTE: We're only adding resources with a @Path annotation on the class level.
