public INewsContentDAO getNewscontentDAO() {

}
public void setNewscontentDAO(INewsContentDAO newscontentDAO) {
this.newscontentDAO = newscontentDAO;
}
换成这样写 注意大小写

请问我的applicationContext.xml中放多个bean 有什么规则吗，我放一个就没错，多了就报错

我没发现有什么问题啊
public class NewsContentServiceSpringImpl implements INewsContentService{

private INewsContentDAO newscontentDAO;

/**

public NewsContentServiceSpringImpl() {
super();
}

/**

public TnewsContent savedt(TnewsContent newscontent) throws Exception{

// do some business logic
TnewsContent tc = null;
try {
tc = this.getNewsContentDAO().savedt(newscontent);
}catch (Exception e) {
throw new Exception("Could not save newscontent " + e.toString());
}
return tc;
}

/**

public INewsContentDAO getNewsContentDAO() {
return newscontentDAO;
}

/**

public void setNewsContentDAO(INewsContentDAO newscontentDAO) {

我的NewsContentHibernateDAO里没有SETTER METHOD啊

public class NewsContentHibernateDAO
extends HibernateDaoSupport
implements INewsContentDAO{

public TnewsContent savedt(final TnewsContent newscontent) {

getHibernateTemplate().save(newscontent);

return newscontent;
}
}

看看 你的类

'newscontentDAO' is not writable or has an invalid setter method

有问题

Spring MVC 入门实例
这篇文章将教你快速地上手使用 Spring 框架. 如果你手上有一本《Spring in Action》, 那么你最好从第三部分"Spring 在 Web 层的应用--建立 Web 层"开始看, 否则那将是一场恶梦! 首先, 我需要在你心里建立起 Spring MVC 的基本概念. 基于 Spring 的 Web 应用程序接收到 http://localhost:8080/hello.do(事实上请求路径是 /hello.do) 的请求后, Spring 将这个请求交给一个名为 helloController 的程序进行处理, helloController 再调用 一个名为 hello.jsp 的 jsp 文件生成 HTML 代码发给用户的浏览器显示. 上面的名称(/hello.do, helloController, hello.jsp) 都是变量, 你可以更改. 在 Spring MVC 中, jsp 文件中尽量不要有 Java 代码, 只有 HTML 代码和"迭代(forEach)"与"判断(if)"两个jstl标签. jsp 文件只作为渲染(或称为视图 View)模板使用. 好了, 我们开始吧. 首先我们需要一个放在 WEB-INF 目录下的 web.xml 文件: web.xml: 1 2 3 7 8 9 contextConfigLocation 10 11 /WEB-INF/database.xml 12 /WEB-INF/applicationContext.xml 13 14 15 16 17 org.springframework.web.context.ContextLoaderListener 18 19 20 21 encodingFilter 22 org.springframework.web.filter.CharacterEncodingFilter 23 24 encoding 25 UTF-8 26 27 28 29 30 encodingFilter 31 *.do 32 33 34 35 ideawu 36 org.springframework.web.servlet.DispatcherServlet 37 1 38 39 40 41

弃用了struts，用spring mvc框架做了几个项目，感觉都不错，而且使用了注解方式，可以省掉一大堆配置文件。本文主要介绍使用注解方式配置的spring mvc，之前写的spring3.0 mvc和rest小例子没有介绍到数据层的内容，现在这一篇补上。下面开始贴代码。 文中用的框架版本：spring 3,hibernate 3,没有的，自己上网下。 先说web.xml配置： [java] view plaincopy 01.<?xml version="1.0" encoding="UTF-8"?> 02. 03. s3h3 04. 05. contextConfigLocation 06. classpath:applicationContext*.xml 07. 08. 09. org.springframework.web.context.ContextLoaderListener 10. 11. 12. 13. spring 14. org.springframework.web.servlet.DispatcherServlet 15. 1 16. 17. 18. spring <!-- 这里在配成spring,下边也要写一个名为spring-servlet.xml的文件，主要用来配置它的controller --> 19. *.do 20. 21. 22. index.jsp 23. 24. spring-servlet,主要配置controller的信息 [java] view plaincopy 01.<?xml version="1.0" encoding="UTF-8"?> 02. 09. 10. 11. <!-- 把标记了@Controller注解的类转换为bean --> 12. 13. <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 --> 14. 15. 16. <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --> 17. 19. 20. 23. applicationContext.xml代码 [java] view plaincopy 01.<?xml version="1.0" encoding="UTF-8"?> 02. 11. 12. 13. <!-- 自动扫描所有注解该路径 --> 14. 15. 16. 17. 19. 20. 21. 22. ${dataSource.dialect} 23. ${dataSource.hbm2ddl.auto} 24. update 25. 26. 27. 28. 29. com.mvc.entity<!-- 扫描实体类，也就是平时所说的model --> 30. 31. 32. 33. 34. 36. 37. 38. 39. 40. 42. 43. 44. 45. 46. 47. <!-- Dao的实现 --> 48. 49. 50. 51. 52. 53. 54. 55. hibernate.properties数据库连接配置 [java] view plaincopy 01.dataSource.password=123 02.dataSource.username=root 03.dataSource.databaseName=test 04.dataSource.driverClassName=com.mysql.jdbc.Driver 05.dataSource.dialect=org.hibernate.dialect.MySQL5Dialect 06.dataSource.serverName=localhost:3306 07.dataSource.url=jdbc:mysql://localhost:3306/test 08.dataSource.properties=user=${dataSource.username};databaseName=${dataSource.databaseName};serverName=${dataSource.serverName};password=${dataSource.password} 09.dataSource.hbm2ddl.auto=update 配置已经完成，下面开始例子 先在数据库建表，例子用的是mysql数据库 [java] view plaincopy 01.CREATE TABLE `test`.`student` ( 02. `id` int(10) unsigned NOT NULL AUTO_INCREMENT, 03. `name` varchar(45) NOT NULL, 04. `psw` varchar(45) NOT NULL, 05.

StringBuffer sff = new StringBuffer(); 20. sff.append("select a from ").append(Student.class.getSimpleName()).append(" a "); 21. List<Object> list = entityDao.createQuery(sff.toString()); 22. return list; 23. } 24. 25. public void save(Student st){ 26. entityDao.save(st); 27. } 28. public void delete(Object obj){ 29. entityDao.delete(obj); 30. } 31.} OK，例子写完。有其它业务内容，只需直接新建view，并实现相应comtroller和service就行了，配置和dao层的内容基本不变，也就是每次只需写jsp（view），controller和service调用dao就行了。 怎样，看了这个，spring mvc是不是比ssh实现更方便灵活。
加载spring时applicationContext.xml文件出错


今天联系Spring+Hibernate基础，没办法，SSH配置一直一直在出问题，只能一点一点的调了~
首先在新建工程的时候就出现了问题，用MyEclipse加入Spring支持的时候就出现了错误提示，T_T~~~~我明明嘛都米开始干呢。。。。。
applicationContext.xml头出现了问题，MyEclipse提示如下错误：
