1 简介

1.1 背景介绍

Java有很多依赖库，而且依赖库的版本不断的更新，在产品开发中，使用新的依赖库，需要更新对应的依赖库的版本信息，往往存在牵一发而动全身的效果。目前公司采用的方法都是人工去查询，然后整理输出到java的配置文件中，需要根据依赖库的artifact去网站https://mvnrepository.com/上逐个查询，这种方法费时费力，且容易出错。而且版本不断的更新，可能要经常去更新依赖配置文件。需要经常去更新依赖库的版本信息；造成大量的时间浪费。为了解决该问题。采用网络爬虫技术，去检索网页中依赖库的版本信息，将依赖库信息抽取出来，然后按照java配置文件中依赖库的pom要求的xml格式和ReadMe需要的格式自动输出依赖关系。

1.2 现有方法优缺点对比

人工查询的具有容易出错、耗时耗力的缺点。而通过工具去查询，具有快速、准确的优点，而且能够按照java配置文件的格式进行输出。无需人为去整理。版本更新迭代时，只需要几秒钟的时间就可以完成人工查询几天的任务量；

2 实现方法

2.1 通过配置文件配置需要查询的依赖库

具体格式和java配置文件中格式相同，如果指定了版本则查询该版本号的依赖库，如果没有指定版本则查询最新版本的依赖库信息，包括groupId，artifactId，version；配置文件的格式如下：

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

<version>1.5.19.RELEASE</version>

</dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-starter-sleuth</artifactId>

</dependency>

<groupId>com.github.pagehelper</groupId>

<artifactId>pagehelper-spring-boot-starter</artifactId>

</dependency>

</dependencies>

2.2 获取最新版本号

读取配置文件中需要查询的依赖库，获取版本信息，没有配置版本号的，通过调用接口从https://mvnrepository.com/查询最新的版本号。

调用接口https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web，https://mvnrepository.com/artifact/+groupid/+artifactid,获取依赖库的版本信息。对应的网页界面如下：

调用接口可以获取到字符串格式的内容，通过观察字符串中的节点名称和组织规律，设计解析算法，获取最新的版本信息。最新的版本信息为2.1.5.RELEASE。

2.3 版本号解析算法实现

int MvnRepository::ParseNewestVersion(string strResponse, Dependence& dep)

{

int pos = strResponse.find("License</th><td><span class=");

string strTemp = "";

if (pos!= string::npos)

{

strResponse = strResponse.substr(pos);

strTemp = strResponse.substr(0, 60);

pos = strTemp.find("b lic");

while (pos!= string::npos)

{

strResponse = strResponse.substr(pos + 7);

pos = strResponse.find("<");

if (pos== string::npos)

{

break;

}

strTemp = strResponse.substr(0, pos);

dep.vecLicense.push_back(strTemp);

strTemp = strResponse.substr(0, 60);

pos= strTemp.find("b lic");

}

pos = strResponse.find("Categories</th><td>");

if (pos!=string::npos)

{

strResponse = strResponse.substr(pos);

strTemp = strResponse.substr(0, 120);

pos = strTemp.find("b c");

while (pos != string::npos)

{

strResponse = strResponse.substr(pos + 5);

pos = strResponse.find("<");

if (pos == string::npos)

{

break;

}

strTemp = strResponse.substr(0, pos);

dep.vecLicense.push_back(strTemp);

strTemp = strResponse.substr(0, 60);

pos = strTemp.find("b c");

}

pos = strResponse.find("vbtn release");

if (pos == string::npos)

{

LOGIC_ERROR("find vbtn release failed");

return HPR_ERROR;

}

strResponse = strResponse.substr(pos + 14);

pos = strResponse.find("<");

if (pos == string::npos)

{

LOGIC_ERROR("find < failed");

return HPR_ERROR;

}

dep.strNewestVersion = strResponse.substr(0, pos);

if (dep.strCurrentVersion=="")

{

dep.strCurrentVersion = dep.strNewestVersion;

}

return HPR_OK;

}

2.4 获取依赖库信息

调用接口获取版本号之后，再调用接口获取依赖库信息，接口为https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web/2.1.5.RELEASE，获取依赖库的Compile Dependencies。同样是解析字符串，按照格式抓取Compile Dependencies信息。保存起来。

2.5 依赖库信息解析算法实现

int MvnRepository::ParseDependences(string strResponse,map<string, Dependence>& mapDependence)

{

int iReval = HPR_ERROR;

int pos = string::npos;

{

if (strResponse=="")

{

break;

}

pos = strResponse.find("Compile Dependencies");

if (pos== string::npos)

{

break;

}

strResponse = strResponse.substr(pos);

pos = strResponse.find("Test Dependencies");

if (pos != string::npos)

{

strResponse=strResponse.substr(0, pos);

}

pos = strResponse.find(" class="b ");

if (pos== string::npos)

{

pos= strResponse.find("vbtn release");

}

string strtemp = "";

while (pos!= string::npos)

{

Dependence dep;

pos = strResponse.find(" class="b ");

if (pos!= string::npos)

{

strResponse = strResponse.substr(pos);

strtemp = strResponse.substr(0, 60);

while (strtemp.find(" class="b ") != string::npos)

{

pos = strtemp.find(" class="b ");

strResponse = strResponse.substr(pos);

pos = strResponse.find(">");

if (pos == string::npos)

{

LOGIC_ERROR("strResponse.find(>) failed");

break;

}

strResponse = strResponse.substr(pos + 1);

pos = strResponse.find("<");

if (pos == string::npos)

{

LOGIC_ERROR("strResponse.find(<) failed");

break;

}

strtemp = strResponse.substr(0, pos);

dep.vecLicense.push_back(strtemp);

LOGIC_TRACE("vecLicense:%s", strtemp.c_str());

strtemp = strResponse.substr(0, 60);

}

pos = strResponse.find("vbtn release");

if (pos== string::npos)

{

LOGIC_ERROR("strResponse.find vbtn release failed!");

break;

}

strResponse = strResponse.substr(pos + 30);

pos = strResponse.find("">");

if (pos== string::npos)

{

LOGIC_ERROR("strResponse.find "> failed!");

break;

}

strtemp = strResponse.substr(0, pos);

strResponse = strResponse.substr(pos);

pos = strtemp.find("/");

if (pos == string::npos)

{

LOGIC_ERROR("strResponse.find / failed!");

break;

}

dep.strGroupid = strtemp.substr(0, pos);

LOGIC_TRACE("strGroupid:%s", dep.strGroupid.c_str());

strtemp = strtemp.substr(pos + 1);

pos = strtemp.find("/");

if (pos == string::npos)

{

LOGIC_ERROR("strResponse.find / failed!");

break;

}

dep.strArtifact = strtemp.substr(0, pos);

LOGIC_TRACE("strArtifact:%s", dep.strArtifact.c_str());

if (dep.strArtifact=="sqljet")

{

int i = 0;

}

strtemp = strtemp.substr(pos + 1);

dep.strCurrentVersion = strtemp;

LOGIC_TRACE("strCurrentVersion:%s", dep.strCurrentVersion.c_str());

strtemp = strResponse.substr(0,120);

pos = strtemp.find("vbtn release");

/*if (pos == string::npos)

{

LOGIC_ERROR("strResponse.find vbtn release failed!");

break;

}

strResponse = strResponse.substr(pos);*/

//pos = strResponse.find(dep.strArtifact);

if (pos != string::npos)

{

strResponse = strResponse.substr(pos);

pos = strResponse.find("">");

if (pos == string::npos)

{

LOGIC_ERROR("strResponse.find "> failed!");

break;

}

strResponse = strResponse.substr(pos + 2);

pos= strResponse.find("<");

if (pos== string::npos)

{

LOGIC_ERROR("strResponse.find "> failed!");

break;

}

strtemp = strResponse.substr(0, pos);

dep.strNewestVersion = strtemp;

LOGIC_TRACE("strNewestVersion:%s", dep.strNewestVersion.c_str());

}

mapDependence[dep.strArtifact + dep.strCurrentVersion]=dep;

pos= strResponse.find(" class="b ");

if (pos==string::npos)

{

pos = strResponse.find("vbtn release");

}

iReval = HPR_OK;

} while (0);

return iReval;

}

3 软件操作步骤

（1）将需要查询的依赖库按照格式输入根目录的pom.xml文件夹下,配置三个选项，如果指定了version，则根据指定的版本去查找，没有指定的库，从网站上查找最新的版本。

<groupId>com.github.pagehelper</groupId>

<artifactId>pagehelper-spring-boot-starter</artifactId>

</dependency>

<groupId>org.springframework.data</groupId>

<artifactId>spring-data-commons</artifactId>

</dependency>

</dependencies>

（2）双击打开JavaDependence.exe软件，点击读取按钮，从配置文件中读取需要查询的库。在对话框中会显示读取的数量；

（3）点击查询按钮进行查询，大概每个3秒左右的时间，慢慢等待。查询结束后，会在对话框中显示成功失败的数量，如果失败了几个，再刷新下网页，然后继续点击查询按钮，会将失败的继续查询，直到所有的都查询成功；

（4）所有的都查询成功后，点击输出按钮进行输出。会按照格式要求输出到文件中。对话框会显示输出成功。Pom.xml中会按照artifact的字母顺序输出。然后在根目录下会有两个文件。
