Java Exception Catch / Throw

Question

我有以下课程：

BusinessException.java （是需要捕获异常并抛出异常的主要异常类）

public class BusinessException
    extends Exception
{
 private BusinessExceptionInfo faultInfo
 public BusinessException(String message, BusinessExceptionInfo faultInfo) {
        super(message);
        this.faultInfo = faultInfo;
    }
 public BusinessException(String message, BusinessExceptionInfo faultInfo, Throwable cause) {
        super(message, cause);
        this.faultInfo = faultInfo;
 }

 public BusinessExceptionInfo getFaultInfo() {
        return faultInfo;
    }
}

BusinessExceptionInfo.java

public class BusinessException {

    protected ExceptionResponse exceptionResponse;
    protected String message;

    // getters and setters for these properties
}

ExceptionResponse.java （此类包含异常消息和堆栈跟踪。此类需要填充来自异常的值）

public class ExceptionResponse {

    protected String exceptionClass;
    protected String exceptionMessage;
    protected List<ErrorResponseItem> errorResponseItems;
    protected String stackTrace;

    // getters and setters for these properties
}

ErrorResponseItem.java

public class ErrorResponseItem {

    protected String defaultErrorDescription;
    protected List<String> descriptionVariables;
    protected String errorCode;
    protected SourceSystemFault sourceSystemFault;

// getter and setter methods
}

// SourceSystemFault.java
public class SourceSystemFault {

    protected List<String> calloutParameters;
    protected String errorCode;
    protected String errorDescription;
    protected String operationName;
    protected String serviceName;
    protected String system;
}

MyClass.java （我的类在哪里需要检查并抛出它。如何传递异常消息，从此类堆栈跟踪到ExceptionResponse？） 任何人都可以分享类似问题的例子。这会很有帮助。我使用这些文件来处理项目中的异常。

public MyResponse myMethod(MyRequest req)
            throws BusinessException {
}

如何捕获并抛出BusinessException。我是新手，需要帮助。
