spring mvc如何去掉Content-Type中的charset

response返回的结果:
Content-Type:audio/mpeg;charset=UTF-8
后台:
response.setContentType("audio/mpeg");
response.setCharacterEncoding("utf-8"); 把这行注释掉,前端看到还有charset=UTF-8
想把charset=UTF-8这段去掉可以吗?

web.xml <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>
false
</param-value> </init-param> </filter> java代码: response.setCharacterEncoding(null); 之前一直不生效是红色的地方为true,改为false,并在后台设置为null即可

手动设为null看下。

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

,之前写的

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

用的框架版本:
spring

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` var
char
(45) NOT NULL, 04. `psw` var
char
(45) NOT NULL, 05. PRIMARY KEY (`id`) 06.) 建好表后,生成实体类 [java] view plaincopy 01.package com.
mvc
.entity; 02. 03.import java.io.Serializable; 04. 05.import javax.persistence.Basic; 06.import javax.persistence.Column; 07.import javax.persistence.Entity; 08.import javax.persistence.GeneratedValue; 09.import javax.persistence.GenerationType; 10.import javax.persistence.Id; 11.import javax.persistence.Table; 12. 13.@Entity 14.@Table(name = "student") 15.public class Student implements Serializable { 16. private static final long serialVersionUID = 1L; 17. @Id 18. @Basic(optional = false) 19. @GeneratedValue(strategy = GenerationType.IDENTITY) 20. @Column(name = "id", nullable = false) 21. private Integer id; 22. @Column(name = "name") 23. private String user; 24. @Column(name = "psw") 25. private String psw; 26. public Integer getId() { 27. return id; 28. } 29. public void
set
Id(Integer id) { 30. this.id = id; 31. } 32. 33. public String getUser() { 34. return user; 35. } 36. public void
set
User(String user) { 37. this.user = user; 38. } 39. public String getPsw() { 40. return psw; 41. } 42. public void
set
Psw(String psw) { 43. this.psw = psw; 44. } 45.} Dao层实现 [java] view plaincopy 01.package com.
mvc
.dao; 02. 03.import java.util.List; 04. 05.public interface EntityDao { 06. public List<Object> createQuery(final String queryString); 07. public Object save(final Object model); 08. public void update(final Object model); 09. public void delete(final Object model); 10.} [java] view plaincopy 01.package com.
mvc
.dao; 02. 03.import java.util.List; 04. 05.import org.hibernate.Query; 06.import org.
spring
framework.orm.hibernate3.HibernateCallback; 07.import org.
spring
framework.orm.hibernate3.support.HibernateDaoSupport; 08. 09.public class EntityDaoImpl extends HibernateDaoSupport implements EntityDao{ 10. public List<Object> createQuery(final String queryString) { 11. return (List<Object>) getHibernateTemplate().execute( 12. new HibernateCallback<Object>() { 13. public Object doInHibernate(org.hibernate.Session session) 14. throws org.hibernate.HibernateException { 15. Query query = session.createQuery(queryString); 16. List<Object> rows = query.list(); 17. return rows; 18. } 19. }); 20. } 21. public Object save(final Object model) { 22. return getHibernateTemplate().execute( 23. new HibernateCallback<Object>() { 24. public Object doInHibernate(org.hibernate.Session session) 25. throws org.hibernate.HibernateException { 26. session.save(model); 27. return null; 28. } 29. }); 30. } 31. public void update(final Object model) { 32. getHibernateTemplate().execute(new HibernateCallback<Object>() { 33. public Object doInHibernate(org.hibernate.Session session) 34. throws org.hibernate.HibernateException { 35. session.update(model); 36. return null; 37. } 38. }); 39. } 40. public void delete(final Object model) { 41. getHibernateTemplate().execute(new HibernateCallback<Object>() { 42. public Object doInHibernate(org.hibernate.Session session) 43. throws org.hibernate.HibernateException { 44. session.delete(model); 45. return null; 46. } 47. }); 48. } 49.} Dao在applicationContext.xml注入
Dao只有一个类的实现,直接供其它service层调用,如果你想更换为其它的Dao实现,也只需修改这里的配置就行了。 开始写view页面,WEB-INF/view下新建页面student.jsp,WEB-INF/view这路径是在
spring
-servlet.xml文件配置的,你可以配置成其它,也可以多个路径。student.jsp代码 [xhtml] view plaincopy 01.<%@ page language="java" contentType="text/html;

spring
就会自动帮你找到相应的bean,相应的注解标记意义,不明白的,可以自己查下@Service,@Controller,@Entity等等的内容。 [java] view plaincopy 01.package com.

是不是比ssh实现更方便灵活。
