本文介绍了一个使用AEM Servlet实现的示例，展示了如何通过Servlet处理HTTP GET和POST请求，包括设置响应类型和字符编码，以及如何与外部服务交互，如Salesforce API调用。

AEM Servlet示例：

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import javax.servlet.ServletException;

import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Properties;
import org.apache.felix.scr.annotations.Property;
import org.apache.felix.scr.annotations.Reference;
import org.apache.felix.scr.annotations.Service;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.apache.sling.commons.json.JSONArray;
import org.apache.sling.commons.json.JSONException;
import org.apache.sling.commons.json.JSONObject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**************************************************************************************
* Java Interface Name : TrialGuideServlet
* Version : 1.0
* Created Date : 8 January 2018

* Function : This class is used for get trial guide message.
* Modification Log :

* *************************************************************************************/

@SuppressWarnings("serial")
@Component(immediate = true, description = "Controller", metatype = true)
@Service(value = javax.servlet.Servlet.class)
@Properties(value = {
       @Property(name = "sling.servlet.methods", value = { "GET", "POST" }),
       @Property(name = "sling.servlet.paths", value = { "/bin/trialguide" }) })
public class TrialGuideServlet extends SlingAllMethodsServlet {
   Logger log = LoggerFactory.getLogger(TrialGuideServlet.class);
   @Reference
   SCGenericMappingService mappingService;

   @SuppressWarnings("null")
   @Override
   protected void doGet(SlingHttpServletRequest req,
           SlingHttpServletResponse response) throws ServletException,
           IOException {
       Boolean isSuccessful = Boolean.TRUE;
       response.setContentType("application/json");
       response.setCharacterEncoding("UTF-8");
       JSONObject returnObject = new JSONObject();

response.getWriter().println(returnObject);

}

注意：

必须指定：

response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");

IE浏览器发出的请求，如不指定，获取不到Response.

另外：get请求会被客户端缓存，如涉及到修改后的获取，可以加时间作为参数刷新数据。

6.4更新：

import java.io.IOException;

import javax.servlet.Servlet;

import javax.servlet.ServletException;

import org.apache.sling.api.SlingHttpServletRequest;

import org.apache.sling.api.SlingHttpServletResponse;

import org.apache.sling.api.servlets.HttpConstants;

import org.apache.sling.api.servlets.SlingAllMethodsServlet;

import org.osgi.framework.Constants;

import org.osgi.service.component.annotations.Component;

import org.osgi.service.component.annotations.Reference;

import com.adobe.cq.mcm.salesforce.SalesforceResponse;

import SFDCConnectorService;

import SFDCConnectorServiceImpl;

@Component(service = Servlet.class, immediate = true,

property = {

"sling.servlet.methods=" + HttpConstants.METHOD_GET,

"sling.servlet.paths" + "=/bin/services/test",

Constants.SERVICE_DESCRIPTION + "= AEM Service API"})

public class SFDCTest extends SlingAllMethodsServlet{

/**

private static final long serialVersionUID = 1L;

@Reference

SFDCConnectorService salesforceService;

final String SERVICE_PATH = "/services/data";

@Override

protected void doGet(final SlingHttpServletRequest req,

final SlingHttpServletResponse resp) throws ServletException, IOException {

// final Resource resource = req.getResource();

// resp.getWriter().write("Title = " + resource.adaptTo(ValueMap.class).get("jcr:title"));

resp.setContentType("application/json");

resp.setCharacterEncoding("UTF-8");

String message = "Test";

resp.getWriter().println(message);

if(salesforceService == null){

message = "salesforceService is null before new it";

resp.getWriter().println(message);

salesforceService = new SFDCConnectorServiceImpl();

}

SalesforceResponse salesforceResponse = salesforceService.executeRequest(SERVICE_PATH,null, null, "GET");

if(salesforceResponse == null){

message = "Salesforce response is null.";

}else{

Integer status = salesforceResponse.getCode();

if(status == 200){

message = salesforceResponse.getBody();

}else{

message = "status: "+status;

}

resp.getWriter().println(message);

}

configuration:

@ObjectClassDefinition(name="PWC salesforce connector",

description = "Properties configuration")

public static @interface Config {

@AttributeDefinition(name = "Cloud services path",

description = "This is the salesforce service path in AEM")

String cloudConfigPath() default "/etc/cloudservices/salesforce/connector";

}

@Activate

public void activate(final Config config) {

this.cloudConfigPath = config.cloudConfigPath();

}
