Struts2 从前端jsp向action传递自定义类型的链表数据

（1）自定义类：

public class AutoTrigger {

private int autoTriggerId;
private String profile;
private int productId;
private int testSuiteId;

public int getAutoTriggerId() {
return autoTriggerId;
}
public void setAutoTriggerId(int autoTriggerId) {
this.autoTriggerId = autoTriggerId;
}
public String getProfile() {
return profile;
}
public void setProfile(String profile) {
this.profile = profile;
}
public int getProductId() {
return productId;
}
public void setProductId(int productId) {
this.productId = productId;
}
public int getTestSuiteId() {
return testSuiteId;
}
public void setTestSuiteId(int testSuiteId) {
this.testSuiteId = testSuiteId;
}

public String toString(){
return "autoTriggerId : "+ autoTriggerId +" profile : " + profile + " productId : " + productId +" testSuiteId : " + testSuiteId;
}

}


（2）对应这个类的转换类
import java.util.Map;

import com.adobe.omniture.bean.AutoTrigger;

import ognl.DefaultTypeConverter;

public class AutoTriggerConverter extends DefaultTypeConverter{
private final String classPattern = "autoTriggerId : (.+) profile : (.+) productId : (.+) testSuiteId : (.+)";
public Object convertValue(Map context, Object value, Class toType){

if(toType == AutoTrigger.class){

String [] params = (String [] )value;
// System.out.println("AutoTriggerconverter: +++++++++++++++++++++params = "+params[0]);
AutoTrigger auto = new AutoTrigger();
String [] attrs = ThucydidesUtilTools.matchs(params[0], classPattern);
auto.setAutoTriggerId(Integer.parseInt(attrs[0].trim()));
auto.setProfile(attrs[1].trim());
auto.setProductId(Integer.parseInt(attrs[2].trim()));
auto.setTestSuiteId(Integer.parseInt(attrs[3].trim()));
return auto;
}else{
AutoTrigger auto = (AutoTrigger)value;
return auto.toString();
}

}

}（3）将他注册为struts2的全局转换类，在xwork-conversion.properties中配置
somepackage.AutoTrigger=somepackage.AutoTriggerConverter

（4）需要的action类
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

import com.adobe.omniture.bean.AutoTrigger;
import com.adobe.omniture.service.AddAutoTriggerService;
import com.opensymphony.xwork2.ActionSupport;

public class AddAutoTriggerAction extends ActionSupport {
private List<AutoTrigger> autoTriggers;
private List<String> testSuiteProfiles, selectedProfiles;
private HashMap<String , Boolean> showProfiles;
private int productId;
private int testSuiteId;
private AddAutoTriggerService addAutoTriggerService;

public AddAutoTriggerAction(){
testSuiteProfiles = new ArrayList<String>();
selectedProfiles = new ArrayList<String>();
showProfiles = new HashMap<String, Boolean>();
autoTriggers = new ArrayList<AutoTrigger>();
}

public String show(){
autoTriggers = addAutoTriggerService.getAutoTrigers(productId);

for(AutoTrigger auto : autoTriggers){

if((auto.getTestSuiteId() == testSuiteId)&&(!testSuiteProfiles.contains(auto.getProfile()))){
testSuiteProfiles.add(auto.getProfile());
}

}

for(AutoTrigger auto : autoTriggers){
String tmpProfile = auto.getProfile();

if(!showProfiles.containsKey(tmpProfile)){
if(testSuiteProfiles.contains(tmpProfile)){
showProfiles.put(tmpProfile, true);
}else{
showProfiles.put(tmpProfile, false);
}
}
}
System.out.println("++++++++++++++++++++++++++++++ in show");

return SUCCESS;
}

public String save(){

System.out.println("++++++++++++++++++++++++++++++ in save");
System.out.println("++++++++++++++++++++++++++++++ autoTriggers = "+autoTriggers.size());
System.out.println("++++++++++++++++++++++++++++++ productId = "+productId);
System.out.println("++++++++++++++++++++++++++++++ testSuiteId = "+testSuiteId);

System.out.println("++++++++++++++++++++++++++++++ testSuiteProfiles = "+testSuiteProfiles.size());
for(String test : testSuiteProfiles){
System.out.println("Profile : "+ test);
}
System.out.println("++++++++++++++++++++++++++++++ selectedProfiles = "+selectedProfiles.size());
for(String test : selectedProfiles){
System.out.println("Profile : "+ test);
}
addAutoTriggerService.saveAutoTriggers(productId, testSuiteId, autoTriggers, testSuiteProfiles, selectedProfiles);
return SUCCESS;
}

public List<AutoTrigger> getAutoTriggers() {
return autoTriggers;
}
public void setAutoTriggers(List<AutoTrigger> autoTriggers) {
this.autoTriggers = autoTriggers;
}
public int getProductId() {
return productId;
}
public void setProductId(int productId) {
this.productId = productId;
}

public int getTestSuiteId() {
return testSuiteId;
}

public void setTestSuiteId(int testSuiteId) {
this.testSuiteId = testSuiteId;
}

public List<String> getTestSuiteProfiles() {
return testSuiteProfiles;
}

public void setTestSuiteProfiles(List<String> testSuiteProfiles) {
this.testSuiteProfiles = testSuiteProfiles;
}

public List<String> getSelectedProfiles() {
return selectedProfiles;
}

public void setSelectedProfiles(List<String> selectedProfiles) {
this.selectedProfiles = selectedProfiles;
}

public AddAutoTriggerService getAddAutoTriggerService() {
return addAutoTriggerService;
}

public void setAddAutoTriggerService(AddAutoTriggerService addAutoTriggerService) {
this.addAutoTriggerService = addAutoTriggerService;
}

public HashMap<String, Boolean> getShowProfiles() {
return showProfiles;
}

public void setShowProfiles(HashMap<String, Boolean> showProfiles) {
this.showProfiles = showProfiles;
}

}
（5）向上面action类传递List<AutoTrigger> 链表的jsp页面
