Weblogic提供商

Question

我创建了一个自定义身份验证提供程序，用于检查数据源中是否存在用户并允许其登录。

现在我还必须检查该用户的角色，但我不了解同一个提供商是否可以处理身份验证和角色映射，或者我是否必须做其他提供商。

我曾尝试为角色映射创建另一个提供程序，但我无法找到它，或者没有找到正确的地方来配置它，但我的MBean类型也没有任何配置插入。

任何人都可以帮我吗？ 我试图找到角色映射的例子，没有运气。

查看Oracle指南：How to Develop a Custom Role Mapping Provider

该过程与创建身份验证提供程序非常相似，唯一的区别是您必须实现的接口。

现在我的实现（我假设您已经创建了一个身份验证提供程序，因此使用WebLogicMBeanMaker了解MBean Provider Creation的知识）： 您需要3个文件，一个包含配置的XML文件，提供者和角色的实现。

配置文件：

<?xml version="1.0" ?>
<!DOCTYPE MBeanType SYSTEM "commo.dtd">

<MBeanType
 Name          = "MYRoleMapper"
 DisplayName   = "MYRoleMapper"
 Package       = "MY.security"
 Extends       = "weblogic.management.security. authorization.RoleMapper"
 PersistPolicy = "OnUpdate"
>
 <MBeanAttribute
  Name          = "ProviderClassName"
  Type          = "java.lang.String"
  Writeable     = "false"
  Preprocessor  = "weblogic.management.configuration.LegalHelper.checkClassName(value)"
  Default       = "&quot;MY.security.MYRoleMapperProviderImpl&quot;"
 />

 <MBeanAttribute
  Name          = "Description"
  Type          = "java.lang.String"
  Writeable     = "false"
  Default       = "&quot;MY RM provider &quot;"
 />

 <MBeanAttribute
  Name          = "Version"
  Type          = "java.lang.String"
  Writeable     = "false"
  Default       = "&quot;1.2&quot;"
 />

</MBeanType>

实际提供者MYRoleMapperProviderImpl.java：

public class MYRoleMapperProviderImpl implements RoleProvider, RoleMapper {
    private String description;
    private static final Map<String, SecurityRole> NO_ROLES = Collections.unmodifiableMap(new HashMap<String, SecurityRole>(1));

    private final static String RESSOURCE_URL = "<url>";
    private final static String RESSOURCE_EJB = "<ejb>";

    private enum rollen {
        READER;
    }

    @Override
    public void initialize(ProviderMBean mbean, SecurityServices services) {
        description = mbean.getDescription() + "\n" + mbean.getVersion();
    }

    @Override
    public String getDescription() {
        return description;
    }

    @Override
    public void shutdown() {

    }

    @Override
    public RoleMapper getRoleMapper() {
        return this;
    }

    @Override
    public Map<String, SecurityRole> getRoles(Subject subject, Resource resource, ContextHandler handler) {
        Map<String, SecurityRole> roles = new HashMap<String, SecurityRole>();
        Set<Principal> principals = subject.getPrincipals();
        for (Resource res = resource; res != null; res = res.getParentResource()) {
            getRoles(res, principals, roles);
        }
        if (roles.isEmpty()) {
            return NO_ROLES;
        }
        return roles;
    }

    private void getRoles(Resource resource, Set<Principal> principals, Map<String, SecurityRole> roles) {
        if (resource.getType() == RESSOURCE_URL || resource.getType() == RESSOURCE_EJB) {
                            roles.put(rollen.READER.toString(), new MYSecurityRoleImpl(rollen.READER.toString(), "READER Rolle"));          
            }
    }
}

绝对简单的角色实施：

package MY.security;

import weblogic.security.service.SecurityRole;

public class MYSecurityRoleImpl implements SecurityRole {

    private String _roleName;
       private String _description;
       private int _hashCode;

       public MYSecurityRoleImpl(String roleName, String description)
       {
          _roleName = roleName;
          _description = description;
          _hashCode = roleName.hashCode() + 17;
       }

       public boolean equals(Object secRole)
       {
          if (secRole == null) 
          {
             return false;
          }

          if (this == secRole) 
          {
             return true;
          }

          if (!(secRole instanceof MYSecurityRoleImpl)) 
          {
             return false;
          }

          MYSecurityRoleImpl anotherSecRole = (MYSecurityRoleImpl)secRole;

          if (!_roleName.equals(anotherSecRole.getName())) 
          {
             return false;
          }

          return true;
       }

       public String toString () { return _roleName; }
       public int hashCode () { return _hashCode; }
       public String getName () { return _roleName; }
       public String getDescription () { return _description; }
}
