dao的方法

public void updateAuthorAdmin(AuthorAdmin aa) {
        try {

            basedao.getTemplate().update(aa);
            System.out.println("dao updateAuthorAdmin suc");
        } catch (Exception e) {
            System.out.println("dao updateAuthorAdmin error");
            e.printStackTrace();
            throw new RuntimeException();
        }
@Override
    public AuthorAdmin getAuthorAdmin(Long id) {
        AuthorAdmin authorAdmin = basedao.getTemplate().get(AuthorAdmin.class,
                id);
        if (authorAdmin == null) {
            System.out.println("dao getAuthorAdmin没有获得对象");
        }
        System.out.println("dao getAuthorAdmin成功获得对象");
        return authorAdmin;
    }

action层

public class AuthorAdminAction extends BaseAction implements
        ModelDriven{
private AuthorAdmin authoradmin = new AuthorAdmin();
    @Override
    public AuthorAdmin getModel() {

        return authoradmin;
    }
public String getAuthorAdmin() {
        authoradmin= iauthoradminservice.getAuthorAdmin(authoradmin.getAuthorId());
        System.out.println("action getAuthorAdmin suc");
        return "getSuccess";

    }
public String updateAuthorAdmin() {
        iauthoradminservice.updateAuthorAdmin(authoradmin);
        System.out.println("action updateAuthorAdmin suc");
        return "updateSuccess";

    }
}

JSP页面根据id跳转

">

进入修改表单

struct2.xml

        
            list_{2}.action
            list_{2}.action
            list_{2}.action
            list_{2}.action
            /{2}/{1}/{1}Success.jsp
            /{2}/update/update.jsp
        

    

实体类的字段还有映射

     private String authorUsername;
     private String authorPwd;
     private String authorName;
     private String authorSex;
