How to get proper special character from string in java?

问题

I am setting a special character in DataModel.
My DataModel

public class LaunchModel implements Serializable {

    private List<LaunchModel> testquestionList;
    public LaunchModel() {
    testquestionList=new ArrayList<LaunchModel>();
    }
    //GETTER AND SETTER
}

My controller method..

private void setdefaultValues() {

    LaunchModel temp=new LaunchModel();
    List<LaunchModel> tempList=new ArrayList<LaunchModel>();
    temp.setQuestion("ΔLMN and ΔXYZ");
    tempList.add(temp);
    this.launchModel.setTestquestionList(tempList);
}

My JSP page..

<h:form id="addAssessmentFormId" enctype="multipart/form-data">
    <t:div id="main" forceId="true">
        <t:dataList id="questionList" var="question"
            value="#{launchPlayer.launchModel.testquestionList}" rowIndexVar="index"
            layout="unorderedList" forceId="true">

            <t:div>
            <h:outputText id="que" value="#{question.question}" />
                <h:inputTextarea id="que" value="#{question.question}" />
            </t:div>
        </t:dataList>
        <t:div style="text-align:center;">
            <h:commandButton value="save" action="#{launchPlayer.testsaveAssessment}"></h:commandButton>
        </t:div>
    </t:div>


</h:form>

回答1:

Set default encoding in your jsp. That should do.

<%@ page language="java" pageEncoding="utf8" contentType="text/html;charset=UTF-8" %>
