如何从Hibernate中的非实体子类持久化实体

对实体进行子类化是否绝对必要？您可以使用构建器模式：

public class ReportBuilder {    private Report report;    public ReportBuilder() {        this.report = new Report();    }    public ReportBuilder setName(String unparsedString) {        // do the parsing        report.setName(parsedString);        return this;    }    public ReportBuilder setValue(String unparsedString) {        // do the parsing        report.setValue(parsedString);        return this;    }    public Report build() {        return report;    }}Report report = new ReportBuilder()        .setName(unparsedString)        .setValue(unparsedString)        .build();dao.saveReport(report);
