Question

我在weblogic 12.2.1.1.0中遇到了con weld和CDI的问题，我有一个名字和代码的类：

    package bo.otracosa;

import java.lang.annotation.Retention;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.util.HashSet;
import java.util.Set;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Default;
import javax.enterprise.inject.Produces;
import javax.inject.Qualifier;
import javax.enterprise.inject.Produces;

/**
 *
 * @author jdlee
 */
@ApplicationScoped
public class Database {

    public Database() {
    }

    private Set<String> authCodes = new HashSet();
    private Set<String> tokens = new HashSet();

    public void addAuthCode(String authCode) {
        authCodes.add(authCode);
    }

    public boolean isValidAuthCode(String authCode) {
        return authCodes.contains(authCode);
    }

    public void addToken(String token) {
        tokens.add(token);
    }

    public boolean isValidToken(String token) {
        return tokens.contains(token);
    }
}

我想用jerset jax-rs注入REST服务，但在REST中我遇到了这个错误：

 :org.jboss.weld.exceptions.DeploymentException:WELD-001409: Ambiguous dependencies for type Database with qualifiers @Default
  at injection point [BackedAnnotatedField] @Inject public bo.sigep.modulo.api.submodulo.AuthzEndPoint.db
  at bo.sigep.modulo.api.submodulo.AuthzEndPoint.db(AuthzEndPoint.java:0)
  Possible dependencies: 
  - Managed Bean [class bo.otracosa.Database] with qualifiers [@Any @Default],
  - Managed Bean [class bo.otracosa.Database] with qualifiers [@Any @Default]

我在其他帖子中发现了这个错误但是解决方案，如何在lib或classpath中找到类重复，在我的情况下不正确。其他解决方案说用户glashfish但我使用weblogic

注入是：

/**

/**

 * @author jdlee
 */
@Path("/authz")
public class AuthzEndPoint {


    @Inject
    public Database db;

    @GET
    public String getMethod() {

        db.isValidToken("hola");
        return "ok";

    }
}

并且不运行任何想法？

Answer 1

错误告诉我们，CDI在类路径上找到bo.otracosa.Database类两次。因此，包含此类的库（jar）不止一次部署。这很难说，但常见的原因是：

您可能已向您的部署添加了两次jar（可能是maven依赖版本问题）
包含bo.otracosa.Database的库可能已经与另一个应用程序或模块一起部署（如果使用maven构建：将依赖关系的范围更改为服务器上已经存在的库provided）

我更新了一个weblogic 12.2.1.2但有效，但是我收到了这个错误：

Caused By: org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=Database,parent=AuthzEndPoint,qualifiers={},position=-1,optional=false,self=false,unqualified=null,1091065126)

Truncated. see log file for complete stacktrace

但我在cdi配置中修改了这个属性：

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       bean-discovery-mode="all">
</beans>

最后工作

weblogic 12.2.1.1.0中的“WELD-001409类型的模糊依赖”
