springmvc+spring+hibernate整合.doc

SpringMVC+Spring+Hibernate整合1、 Spring + SpringMVC +Hibernate集成步骤。1、集成Spring框架：编写spring的配置文件在web.xml中通过监听器加载spring的配置文件2、集成Hibernate框架：在spring的配置文件中，配置sessionFactory对象。为sessionFactory对象注入Hibernate相关属性配置transactionManager事务管理器3、集成spring mvc框架：编写spring mvc的配置文件在web.xml中注册DispatcherServlet，加载spring mvc配置文件4、在web.xml中注册常用的过滤器：字符集过滤器和OpenSessionInView过滤器等。1. 导入相应的JAR包项目结构编写perties 文件#mysql configjdbc.url=jdbc:mysql:/testjdbc.driver=com.mysql.jdbc.Driverjdbc.username=rootjdbc.password=root编写 日志properties 文件og4j.rootLogger=INFO, stdout, logfilelog4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d %p %c - %m%nlog4j.appender.logfile=org.apache.log4j.RollingFileAppenderlog4j.appender.logfile.File=project-log.loglog4j.appender.logfile.MaxFileSize=512KB# Keep three backup files.log4j.appender.logfile.MaxBackupIndex=3# Pattern to output: date priority category - messagelog4j.appender.logfile.layout=org.apache.log4j.PatternLayoutlog4j.appender.logfile.layout.ConversionPattern=%d %p %c - %m%n6. 编写Spring 配置文件,开启组件自动扫描，加载属性文件，配置持久层（数据源，SessionFactory），事物管理，及JSR303验证beans.xml classpath*:com/nyf/entity/hibernate.dialet=org.hibernate.dialect.MySQL5Dialecthibernate.show_sql=truehibernate.hbm2ddl.auto=update 2. 编写相应的实体类Com.nyf.entity.Userpackage com.nyf.entity;import java.util.*;public class User private Integer id;/*姓名*/private String name;/*年龄*/private int age;/*生日*/private Date birthday = new Date();/*电话*/private String phone;/*Email*/private String mail;/*性别*/private int gender;/0女1男/*身份证*/private String idcard;/*地址*/private String address;/*职位*/private String position;/*密码*/private String password;public Integer getId() return id;public void setId(Integer id) this.id = id;public String getName() return name;public void setName(String name) = name;public int getAge() return age;public void setAge(int age) this.age = age;public Date getBirthday() return birthday;public void setBirthday(Date birthday) this.birthday = birthday;public String getPhone() return phone;public void setPhone(String phone) this.phone = phone;public String getMail() return mail;public void setMail(String mail) this.mail = mail;public int getGender() return gender;public void setGender(int gender) this.gender = gender;public String getIdcard() return idcard;public void setIdcard(String idcard) this.idcard = idcard;public String getAddress() return address;public void setAddress(String address) this.address = address;public String getPosition() return position;public void setPosition(String position) this.position = position;public String getPassword() return password;public void setPassword(String password) this.password = password;Overridepublic String toString() return name+, +age+, +birthday+, +phone+, +mail+, +gender+, +idcard+, +address+, +position+, +password;3.
