如何从Java访问Primefaces DataTable行

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.ViewScoped;
import org.primefaces.model.TreeNode;

@ManagedBean
@ViewScoped
public class DataTableBean {
    @ManagedProperty("#{yourManagedBean}")
    private YourManagedBean yourManagedBean;

    public void setYourManagedBean(YourManagedBean yourManagedBean) {
        this.yourManagedBean = yourManagedBean;
    }

    public void handleSelectedRows() {
        List<YourDataObject> selectedRows = yourManagedBean.getDataTable().getSelectedRowsData();
        
        // 处理选中行的数据
        for (YourDataObject row : selectedRows) {
            // 对选中行的数据进行操作
            // ...
        }
    }
}
