Question

嗨，我正在无限循环中连续不断地从逻辑复制流中读取数据。我有另一个程序正在不断地填充同一数据库中的表。我注意到一段时间后（大约5-10分钟）。我总是有例外

package com.sanju.p1; 
//webfault and namespace
@WebFault(name = "getPreAHistFlt", targetNamespace = "http://www.getPreAuthorizationHistory") 
public class getPreAHistFltMsg extends Exception { 

    private com.sanju.p2.GetPreAHistFlt getPreAHistFlt;   // showing bug here 
//constructors
    public getPreAHistFltMsg() { 
        super(); 
    } 

    public getPreAHistFltMsg(String message) { 
        super(message); 
    } 

    public getPreAHistFltMsg(String message, Throwable cause) { 
        super(message, cause); 
    } 

    public getPreAHistFltMsg(String message, com.sanju.p2.GetPreAHistFlt getPreAHistFlt) { 
        super(message); 
        this.getPreAHistFlt = getPreAHistFlt; 
    } 

    public getPreAHistFltMsg(String message, com.sanju.p2.GetPreAHistFlt getPreAHistFlt, Throwable cause) { 
        super(message, cause); 
        this.getPreAHistFlt = getPreAHistFlt; 
    } 

    public com.sanju.p2.GetPreAHistFlt getFaultInfo() { 
        return this.getPreAHistFlt; 
    } 
}

这是我的示例程序：

}

任何帮助都值得赞赏！！我正在使用postgres JDBC驱动程序42.2.2。
