项目使用Struts2+spring2.0+hibernate3.2
BookAction.java
public class BookAction extends BaseAction{
private BookManager bookManager;
private Book book;
private List books;
private Integer id;
private Boolean isNew;
public void setBookManager(BookManager bookManager) {
this.bookManager = bookManager;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getId() {
return id;
}
public void setIsNew(Boolean isNew) {
this.isNew = isNew;
}
public Book getBook() {
return book;
}
public void setBook(Book book) {
this.book = book;
}
public List getBooks(){
return books;
}
public String delete() throws IOException {
String[] ids = getRequest().getParameterValues("itemlist");
int success = 0;
if (ids != null) {
for (int i = 0; i < ids.length; i++) {
String id = ids[i];
try {
bookManager.removeBook(bookw Integer(id));
success++;
}
catch (DataIntegrityViolationException e) {
}
}
saveMessage("成功删除" + success + "条纪录!");
}
return SUCCESS;
}
public String edit() throws IOException {
if (isNew == false && id != null) {
book = bookManager.getBook(id);
}else {
book = new Book();
}
return SUCCESS;
}
public String save() throws Exception {
try{
bookManager.saveBook(book);
}catch(Exception e){
return INPUT;
}
return SUCCESS;
}
public String list() {
books = bookManager.getAllBook();
return SUCCESS;
}
}
action在spring中配置:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans default-autowire="byName" default-lazy-init="true">
<bean id="bookAction" class="com.meetyou930.action.BookAction"/>
</beans>
有个问题是:
1、如果我在这个配置中加上,singleton="false",那么当我修改后保存的时候,将会新增一条记录,而不是修改。而且struts2的服务器端校验也不好使。
2、使用默认的singleton="true",多人操作的时候是否会有问题?
另外,哪位有写的比较好的BaseAction类希望能共享一下,我现在用的是appfuse的。
