我想在WildFly Swarm中运行一个简单的实体 - 控制器 - boundery应用程序。这工作正常，但是当我添加一个ExceptionMapper来捕获NotFoundException这可以在WildFly服务器10上工作，但不在WildFly群集中。这是Shrinkwrap中的错误吗？这是Wildfly Swarm中的一个bug吗？或者我在收缩包装部署方面做错了什么？Excpetionmapper不适用于Wildfly Swarm，但在蜻蜓服务器中工作
下面是该群主类的特定代码：
public class Main {
public static void main(String[] args) throws Exception {
Container container = new Container();
container.fraction(new DatasourcesFraction()
.jdbcDriver("h2", (d) -> {
d.driverClassName("org.h2.Driver");
d.xaDatasourceClass("org.h2.jdbcx.JdbcDataSource");
d.driverModuleName("com.h2database.h2");
})
.dataSource("demoDS", (ds) -> {
ds.driverName("h2");
ds.connectionUrl("jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
ds.userName("sa");
ds.password("sa");
})
);
// Prevent JPA Fraction from installing it's default datasource fraction
container.fraction(new JPAFraction()
.inhibitDefaultDatasource()
.defaultDatasource("jboss/datasources/demoDS")
);
container.start();
JAXRSArchive deployment = ShrinkWrap.create(JAXRSArchive.class);
deployment.addClasses(Customer.class);
deployment.addAsWebInfResource(new ClassLoaderAsset("META-INF/persistence.xml", Main.class.getClassLoader()), "classes/META-INF/persistence.xml");
deployment.addClass(CustomerService.class);
deployment.addResource(CustomerResource.class);
//BUG: The provider below is not working!
deployment.addClass(NotFoundExceptionMapper.class);
deployment.addAllDependencies();
container.deploy(deployment);
}
}
，这里是我的群演示pom.xml：

为了便于比较，这是我的Wildfly服务器应用pom.xml：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

为了完整，这里是代码fo R上的ExceptionMapper：
@Provider
public class NotFoundExceptionMapper implements ExceptionMapper<NotFoundException> {
@Override
public Response toResponse(NotFoundException e) {
System.out.println("Exceptionmapper called!");
return Response.ok().build();
}
}
的boundery：
控制器：
@Stateless
public class CustomerService {
@PersistenceContext
private EntityManager em;
public List<Customer> getAll() {
return em.createNamedQuery(Customer.FIND_ALL, Customer.class).getResultList();
}
}
和实体：
@Entity @Table(name = "CUSTOMER")
@NamedQueries({@NamedQuery(name = Customer.FIND_ALL, query = "SELECT c FROM Customer c")})
@XmlRootElement
public class Customer implements Serializable {
public static final String FIND_ALL = "Customer.findAll";
private static final long serialVersionUID = 1L;
@Id @GeneratedValue(strategy = GenerationType.AUTO)
private int id;
@Column(length = 40)
private String name;
public Customer() { }
public Customer(String name) { this.name = name; }
public int getId() { return id; }
protected void setId(int id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
// toString, equals and hashCode overrides omitted
}
谢谢肯！你真棒！ –
