java - java.lang.NumberFormatException：对于输入字符串“v2.6.5.2”

问题描述

我正在使用 java 实现 RPC(JSON) 系统，但在回答其中一个调用时遇到错误。

SperoCoin.java

1 package com.l2spero.gameserver.handler.voicedcommandhandlers;
2    public class SperoCoin
3    {
4       public NpcHtmlMessage nhm = new NpcHtmlMessage(5);
5       public TextBuilder replyMSG = new TextBuilder("");
6       
7       public String address = "127.0.0.1";
8       public int port = 55681;
9       public String protocol = "http";
10      public String user = "user";
11      public String password = "password";
12      
13      BitcoindApi api = BitcoindApiFactory.createConnection(address, port, protocol, user, password);
14    
15      
16      public void getInfo(String[] args) throws BitcoindConnector4JException
17      {
18          try {
19              Info info = api.getinfo();
20              BlockchainInfo getblockchaininfo = api.getblockchaininfo();
21              
22                  replyMSG.append("<html><title>SPEROCOIN WALLET</title><body>");
23                  replyMSG.append("<font color=\"FFFF00\"><center>L2SPERO WALLET</center></font>");

30                  
31          }catch (Exception e) {
32              e.printStackTrace();
33          }
34      }
35    }

上面的文件显示了我在 JAVA 应用程序中需要的文本，但是第 24 行，当我运行命令时出现错误：

读取失败：[C] 38 Say2 ；java.lang.NumberFormatException：对于输入字符串：“v2.6.5.2：Beta 2.6.5.2”com.l2spero.sperocoin.core.BitcoindConnector4JException：java.lang.NumberFormatException：对于输入字符串：“v2.6.5.2：Beta 2.6.5.2"

在外部应用程序内部进行调用并以 JSON 格式返回结果的 Info.java 文件是这样的：

package com.l2spero.sperocoin.response;

public class Info extends BaseResponse {

    private Double balance;
    private long blocks;
    private long connections;
    private Double difficulty;
    private String errors;
    private long keypoololdest;
    private long keypoolsize;
    private Double paytxfee;
    private long protocolversion;
    private String proxy;
    private Double relayfee;
    private boolean testnet;
    private long timeoffset;
    private long version;
    private long walletversion;

    public Double getBalance() {
        return balance;
    }

    public void setBalance(Double balance) {
        this.balance = balance;
    }

    public long getBlocks() {
        return blocks;
    }

    public void setBlocks(long blocks) {
        this.blocks = blocks;
    }

    public long getConnections() {
        return connections;
    }

    public void setConnections(long connections) {
        this.connections = connections;
    }

    public Double getDifficulty() {
        return difficulty;
    }

    public void setDifficulty(Double difficulty) {
        this.difficulty = difficulty;
    }

    public String getErrors() {
        return errors;
    }

    public void setErrors(String errors) {
        this.errors = errors;
    }

    public long getKeypoololdest() {
        return keypoololdest;
    }

    public void setKeypoololdest(long keypoololdest) {
        this.keypoololdest = keypoololdest;
    }

    public long getKeypoolsize() {
        return keypoolsize;
    }

    public void setKeypoolsize(long keypoolsize) {
        this.keypoolsize = keypoolsize;
    }

    public Double getPaytxfee() {
        return paytxfee;
    }

    public void setPaytxfee(Double paytxfee) {
        this.paytxfee = paytxfee;
    }

    public long getProtocolversion() {
        return protocolversion;
    }

    public void setProtocolversion(long protocolversion) {
        this.protocolversion = protocolversion;
    }

    public String getProxy() {
        return proxy;
    }

    public void setProxy(String proxy) {
        this.proxy = proxy;
    }

    public Double getRelayfee() {
        return relayfee;
    }

    public void setRelayfee(Double relayfee) {
        this.relayfee = relayfee;
    }

    public boolean getTestnet() {
        return testnet;
    }

    public void setTestnet(boolean testnet) {
        this.testnet = testnet;
    }

    public long getTimeoffset() {
        return timeoffset;
    }

    public void setTimeoffset(long timeoffset) {
        this.timeoffset = timeoffset;
    }

    public long getVersion() {
        return version;
    }

    public void setVersion(long version) {
        this.version = version;
    }

    public long getWalletversion() {
        return walletversion;
    }

    public void setWalletversion(long walletversion) {
        this.walletversion = walletversion;
    }

    @Override
    public String toString() {
        return "GetInfo [balance=" + balance + ", blocks=" + blocks + ", connections=" + connections + ", difficulty="
                + difficulty + ", errors=" + errors + ", keypoololdest=" + keypoololdest + ", keypoolsize="
                + keypoolsize + ", paytxfee=" + paytxfee + ", protocolversion=" + protocolversion + ", proxy=" + proxy
                + ", relayfee=" + relayfee + ", testnet=" + testnet + ", timeoffset=" + timeoffset + ", version="
                + version + ", walletversion=" + walletversion + "]";
    }

}

源应用程序中 JSON 的返回是这样的：

{
"version" : "v2.6.5.2: Beta 2.6.5.2",
"protocolversion" : 700004,
"walletversion" : 60000,
"balance" : 0.00000000,
