Salesforce中经过SOAP API开发java的web service服务以及踩坑

1.下载Salesforce平台中WSDL文件

首先须要的是本身Salesforce平台的权限经过。登录本身的Salesforce，下载WSDL文件。html

依次点击右上角你的名字中设置--》集成--》APIjava

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，便可，以下两图显示：api

分别下点生成企业WSDL，生成合做伙伴WSDL，生成元数据WSDL安全

点击鼠标右键将文件另保存，可为.xml的形式也能够为.wsdl的文件形式框架

2.下载并构建WSC Jar，而后把对应的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jsp

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）测试

ST4-4.0.8.jar (https://www.stringtemplate.org/download.html)spa

若是没有会报错：3d

Exception in thread "main" java.lang.NoClassDefFoundError:org/stringtemplate/v4/STGroupDirxml

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（如下enterprise.jar，metadata.jar，partner.jar是经过下面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.建立程序并引用外部jar文件

建立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建立一个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帐号中的用户名
   static final String PASSWORD = "YOUR-PASSWORD&security token"; //密码，这个密码有点特殊，须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）

根据控制台ID能够去salesforce查询到该客户

若是须要用到新的对象，好比我本身建立的Position对象，那么能够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，以下图

找到对应的api名称后，若是须要建立一条Position纪录，那么能够这样new一个对象 Position__c a = new Position__c(); 而后经过Set的扩展方法来对对象字段的值进行赋值即可。
