您必须像这样在托管bean中编写一些Java代码：

public class SomethingSomethingDTO {
    private final String subject;
    private final String evaluation;
    private final String comment;

    public SomethingSomethingDTO(final String subject, 
            final String evaluation, final String comment) {
        this.subject = subject;
        this.evaluation = evaluation;
        this.comment = comment;
    }

    public String getSubject() {
        return subject;
    }

    public String getEvaluation() {
        return evaluation;
    }

    public String getComment() {
        return comment;
    }

}

@PostConstruct // or some other event or command button action
public void initializeSomething() {
    somethings = new ArrayList<>();
    somethings.add(new SomethingSomethingDTO("training", "A", "..."));
    somethings.add(new SomethingSomethingDTO("experiance", "B", "..."));
}

private List<SomethingSomethingDTO> somethings;

public List<SomethingSomethingDTO> getSomethings() {
    return somethings;
}
