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

package com.yipan;

import com.sforce.soap.enterprise.Connector; import com.sforce.soap.enterprise.EnterpriseConnection; import com.sforce.soap.enterprise.QueryResult; import com.sforce.soap.enterprise.SaveResult; import com.sforce.soap.enterprise.sobject.Account;

import com.sforce.ws.ConnectionException; import com.sforce.ws.ConnectorConfig;

public class Test { static final String USERNAME = "YOUR-USERNAME"; //Salesforce账号中的用户名 static final String PASSWORD = "YOUR-PASSWORD&security token"; //密码，这个密码有点特殊，需要在密码后面加入安全标记 static EnterpriseConnection connection;

public static void main(String[] args) {

ConnectorConfig config = new ConnectorConfig(); config.setUsername(USERNAME); config.setPassword(PASSWORD); try { connection = Connector.newConnection(config); System.out.println("Auth EndPoint: "+config.getAuthEndpoint()); System.out.println("Service EndPoint: "+config.getServiceEndpoint()); System.out.println("Username: "+config.getUsername()); System.out.println("SessionId: "+config.getSessionId());

// 增删改查 queryContacts(); //createAccounts(); //updateAccounts(); //deleteAccounts(); } catch (ConnectionException e1) { e1.printStackTrace(); }

} // queries and displays the 5 newest contacts private static void queryContacts() { System.out.println("Querying for the 5 newest Account..."); try { // query for the 5 newest contacts //SELECT Id, FirstName, LastName, Account.Name " + "FROM Contact WHERE AccountId != NULL ORDER BY CreatedDate DESC LIMIT 5 QueryResult queryResults = connection.query("SELECT Id, Name,NumberOfEmployees FROM Account WHERE ID !=NULL ORDER BY CreatedDate DESC LIMIT 5"); if (queryResults.getSize() > 0) { for (int i=0;i<queryResults.getRecords().length;i++) { // cast the SObject to a strongly-typed Contact //Contact c = (Contact)queryResults.getRecords()[i]; Account c=(Account)queryResults.getRecords()[i]; System.out.println("Id: " + c.getId() + " - Name: "+c.getName()+"NumberOfEmployees: "+c.getNumberOfEmployees()); } } } catch (Exception e) { e.printStackTrace(); } } // create 5 test Accounts private static void createAccounts() { System.out.println("Creating 5 new test Accounts..."); Account[] records = new Account[2]; try { // create 5 test accounts for (int i=0;i<2;i++) { Account a = new Account(); a.setName("hello"+i); records[i] = a; } // create the records in Salesforce.com SaveResult[] saveResults = connection.create(records); // check the returned results for any errors for (int i=0; i< saveResults.length; i++) { if (saveResults[i].isSuccess()) { System.out.println(i+". Successfully created record - Id: " + saveResults[i].getId()); } else { com.sforce.soap.enterprise.Error[] errors = saveResults[i].getErrors(); for (int j=0; j< errors.length; j++) { System.out.println("ERROR creating record: " + errors[j].getMessage()); } } } } catch (Exception e) { e.printStackTrace(); } } // updates the 5 newly created Accounts private static void updateAccounts() { System.out.println("Update the 5 new test Accounts..."); Account[] records = new Account[5]; try { QueryResult queryResults = connection.query("SELECT Id, Name FROM Account ORDER BY " + "CreatedDate DESC LIMIT 5"); if (queryResults.getSize() > 0) { for (int i=0;i<queryResults.getRecords().length;i++) { // cast the SObject to a strongly-typed Account Account a = (Account)queryResults.getRecords()[i]; System.out.println("Updating Id: " + a.getId() + " - Name: "+a.getName()); // modify the name of the Account a.setName(a.getName()+" -- UPDATED"); records[i] = a; } } // update the records in Salesforce.com SaveResult[] saveResults = connection.update(records); // check the returned results for any errors for (int i=0; i< saveResults.length; i++) { if (saveResults[i].isSuccess()) { System.out.println(i+". Successfully updated record - Id: " + saveResults[i].getId()); } else { com.sforce.soap.enterprise.Error[] errors = saveResults[i].getErrors(); for (int j=0; j< errors.length; j++) { System.out.println("ERROR updating record: " + errors[j].getMessage()); } } } } catch (Exception e) { e.printStackTrace(); } } // delete the 5 newly created Account private static void deleteAccounts() { System.out.println("Deleting the 5 new test Accounts..."); String[] ids = new String[5]; try { QueryResult queryResults = connection.query("SELECT Id, Name FROM Account ORDER BY " + "CreatedDate DESC LIMIT 5"); if (queryResults.getSize() > 0) { for (int i=0;i<queryResults.getRecords().length;i++) { // cast the SObject to a strongly-typed Account Account a = (Account)queryResults.getRecords()[i]; // add the Account Id to the array to be deleted ids[i] = a.getId(); System.out.println("Deleting Id: " + a.getId() + " - Name: "+a.getName()); } } // delete the records in Salesforce.com by passing an array of Ids com.sforce.soap.enterprise.DeleteResult[] deleteResults = connection.delete(ids); // check the results for any errors for (int i=0; i< deleteResults.length; i++) { if (deleteResults[i].isSuccess()) { System.out.println(i+". Successfully deleted record - Id: " + deleteResults[i].getId()); } else { com.sforce.soap.enterprise.Error[] errors = deleteResults[i].getErrors(); for (int j=0; j< errors.length; j++) { System.out.println("ERROR deleting record: " + errors[j].getMessage()); } } } } catch (Exception e) { e.printStackTrace(); } }

} 运行项目（在此截图查询的记录，其它的都测试过了）
