Struts 2 Iterator tag sample code
Below sample example you will see how to use Struts 2 iterator tag where we will print value from the list using property tag.
- Create maven project name: Struts2Iterator
- Project structure:
- pom.xml dependency:
<dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.3.16.3</version> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-convention-plugin</artifactId> <version>2.3.16.3</version> </dependency>
- IteratorTagExampleAction.java
package com.javahonk.action; import java.util.ArrayList; import java.util.List; import org.apache.struts2.convention.annotation.Action; import org.apache.struts2.convention.annotation.Result; import org.apache.struts2.convention.annotation.Results; import com.opensymphony.xwork2.ActionSupport; @Results({ @Result(name = "error", location = "/iterator.jsp"), @Result(name = "input", location = "/iterator.jsp")}) public class IteratorTagExampleAction extends ActionSupport { private static final long serialVersionUID = 1L; private List<Person> personList = new ArrayList<Person>(); @Override @Action(value = "/iteratorTagExampleAction") public String execute() throws Exception { personList.add(new Person("Java", "Honk", "NY")); personList.add(new Person("Ramesh", "Arrepu", "NY")); personList.add(new Person("Igor", "Vornovitsky", "NY")); personList.add(new Person("Bob", "Sidebottom", "NY")); personList.add(new Person("Sunil", "Garg", "NY")); personList.add(new Person("Mike", "Lee", "NY")); return ActionSupport.INPUT; } public List<Person> getPersonList() { return personList; } public void setPersonList(List<Person> personList) { this.personList = personList; } }
- Person.java
package com.javahonk.action; import java.io.Serializable; public class Person implements Serializable{ private static final long serialVersionUID = 1L; private String firstName; private String lastName; private String location; public Person(String firstName, String lastName, String location) { super(); this.firstName = firstName; this.lastName = lastName; this.location = location; } public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public String getLocation() { return location; } public void setLocation(String location) { this.location = location; } }
- iterator.jsp:
