There may be some issues because the "for loop" does not call the method "doneLatch.countDown", and the main thread will be suspended forever. In a word, it seems that the callback function has been losted. Should it be like this:
for (int i = 0; i < MAX_COUNT; i++) { final WebTarget endpoint = target().path("broadcast/book").queryParam("clientId", i + 1); readerEventSources[i] = EventSource.target(endpoint).build(); readerEventSources[i].register(new EventListener(){ @Override public void onEvent(InboundEvent inboundEvent) { try{ String data = inboundEvent.readData(String.class); System.out.println("What the server response: " + inboundEvent.getId() + " : " +inboundEvent.getName() + " : " + data); Assert.assertEquals(newBookName,data); doneLatch.countDown(); }catch (ProcessingException e){ System.out.println(e.getMessage()); } } }); }

另外还有59个漏洞，详细报告：https://mofeisec.com/jr?p=i759e1

The file (5.jaxrs2-client/pom.xml) includes broken dependency reference.

  <dependency>
      <groupId>com.example</groupId>
      <artifactId>example-common</artifactId>
      <version>1.0-SNAPSHOT</version>
  </dependency>

Also redundant import (import org.springframework.boot.actuate.system.ApplicationPidFileWriter; and import javax.ws.rs.container.PreMatching;) in file (com.example.BootConsulApplication).
And redundant import (import javax.persistence.*;) in file (com.example.client.entity.Book).

运行jetty后，输入curl命令如下：
curl -X POST http://localhost:8080/webapi/myresource -d '' -H "Content-type:application/xml"
提示：系统找不到指定文件

需要降低junit的版本或者添加hamcrest的jar

您好，我在使用jersey集成springboot的时候，使用了@FormParam，后台就提示这个问题。使用postman测试，后台业务还是能运行的，使用swagger editor就不行了。

本章节多处GlassFish被误引为GlashFish，反馈一下。

jax-rs2-guide-II/5.jaxrs2-client/src/main/java/com/example/client/PoolingClient.java

读书的时候看到这块感觉很奇怪, 因为Client是要尽量重用的, 而且这里的程序里PoolingClient 构造函数明明创建了一个支持connection pool 的client 实例变量.

下面的 "//关注点1：构造Client" 应该删掉吧?

public T rest(String method, String requestUrl,
                  Set<Pair<String, Object>> headParams, Set<Pair<String, Object>> queryParams,
                  MediaType requestDataType, Class<T> returnType, T requestData) {
        //关注点1：构造Client
        if (clientConfig == null) {
            clientConfig = new ClientConfig();
        }
        Client client = ClientBuilder.newClient(clientConfig);
