2019独角兽企业重金招聘Python工程师标准>>> 
1.下载Salesforce平台中WSDL文件
首先需要的是自己Salesforce平台的权限通过。登陆自己的Salesforce，下载WSDL文件。
依次点击右上角你的名字中设置--》集成--》API
在页面上选择要生成WSDL的类型，在弹出的页面选择 右键 -->页面另存为，即可，如下两图显示：
分别下点生成企业WSDL，生成合作伙伴WSDL，生成元数据WSDL
点击鼠标右键将文件另保存，可为.xml的形式也可以为.wsdl的文件形式
2.下载并构建WSC Jar，然后把对应的wsdl文件编译成对应jar
Wsc.jar 下载地址：https://mvnrepository.com/artifact/com.force.api/force-wsc 选择最新版本的
选择下图中的jar就能下载jar包到本地啦（对应jdk版本1.8或者以上）
ST4-4.0.8.jar (https://www.stringtemplate.org/download.html)
如果没有会报错：
Exception in thread "main" java.lang.NoClassDefFoundError:org/stringtemplate/v4/STGroupDir
Antlr-runtime-3.5.2.jar (https://mvnrepository.com/artifact/org.antlr/antlr-runtime/3.5.2)
用于java代码运行时构造，编译，转换的框架。
没有的话报错：
Exception in thread "main" java.lang.NoClassDefFoundError: org/antlr/runtime/CharStream
Tools.jar （安装jdk的目录下有，无需下载。直接复制）
把刚才下载的jar包和3个wsdl文件放在同一个文件夹中（以下enterprise.jar，metadata.jar，partner.jar是通过下面cmd命令生成jar的）
打开cmd，将路径定位到刚才的文件目录。
输入 java -classpath antlr-runtime-3.5.2.jar;tools.jar;st4-4.0.4.jar;force-wsc-45.1.0.jar com.sforce.ws.tools.wsdlc wsdl.xml enterprise.jar
java -classpath antlr-runtime-3.5.2.jar;tools.jar;st4-4.0.4.jar;force-wsc-45.1.0.jar com.sforce.ws.tools.wsdlc wsdl.jsp.xml partner.jar
java -classpath antlr-runtime-3.5.2.jar;tools.jar;st4-4.0.4.jar;force-wsc-45.1.0.jar com.sforce.ws.tools.wsdlc metadata.xml metadata.jar
3.创建程序并引用外部jar文件
创建java程序和引用jar外部包我就不解释，要应用的jar就是上文生成的3个jar（enterprise.jar，metadata.jar，partner.jar），对，也要 force-wsc-45.1.0.jar
打开Eclipse创建一个JAVA项目，将上面说的四个jar包引进项目。
贴上接口代码，本例用的salesforce自带的对象Accout

运行项目（在此截图查询的记录，其它的都测试过了）
根据控制台ID可以去salesforce查询到该客户
如果需要用到新的对象，比如我自己创建的Position对象，那么可以在对象的详细页面找到对象对应的api名称，以及对象中字段api名称，如下图
找到对应的api名称后，如果需要创建一条Position纪录，那么可以这样new一个对象 Position__c a = new Position__c(); 然后通过Set的扩展方法来对对象字段的值进行赋值便可。
