一建表
cat表
代码
CREATE TABLE cat (
cat_id varchar() NOT NULL
NAME varchar() NOT NULL
sex CHAR()
weight FLOAT
PRIMARY KEY (cat_id)
);
二po层（系统以cathbmxml为准一个xml可以写多个class）
Xml代码
<<<<<<<<<<<<<cathbmxml>>>>>>>>>>>>>>>>>>>>>>>
<?xml version=?>
<!DOCTYPE hibernatemapping PUBLIC //Hibernate/Hibernate Mapping DTD//EN mappingdtd>
<hibernatemapping>
<class name=easewirelessgroupsmshbntpoCat table=cat>
<id name=id type=string unsavedvalue=null >
<column name=cat_id sqltype=varchar() notnull=true/>
<generator class=uuidhex/>
</id>
<property name=name>
<column name=NAME sqltype=varchar() notnull=true/>
</property>
<property name=sex/>
<property name=weight/>
</class>
</hibernatemapping>
Java代码
<<<<<<<<<<<<<Catjava>>>>>>>>>>>>>>>>>>>>>>>>>
package easewirelessgroupsmshbntpo;
public class Cat {
private String id;
private String name;
private char sex;
private float weight;
public Cat() {
}
public String getId() {
return id;
}
public void setId(String id) {
thisid = id;
}
public String getName() {
return name;
}
public void setName(String name) {
thisname = name;
}
public char getSex() {
return sex;
}
public void setSex(char sex) {
thissex = sex;
}
public float getWeight() {
return weight;
}
public void setWeight(float weight) {
thisweight = weight;
}
public String toString() {
String strCat = new StringBuffer()
append(thisgetId())append( )
append(thisgetName())append( )
append(thisgetSex())append( )
append(thisgetWeight())
toString();
return strCat;
}
}
三hibernatecfgxml
（切切不要自己去加属性基本的就两个connectiondatasource和dialect）
Xml代码
<property name=connectionusername>root</property>
<property name=connectionpassword>root</property>
<property name=connectionprovider_class>nnectionDatasourceConnectionProvider</property>
<property name=jndiclass>orggjtmmmysqlDriver</property>
<<<<<<<<<<<<<hibernatecfgxml>>>>>>>>>>>>>>>>>>>>>>>
<?xml version= encoding=UTF?>
<!DOCTYPE hibernateconfiguration PUBLIC
//Hibernate/Hibernate Configuration DTD //EN
configurationdtd>
<! DO NOT EDIT: This is a generated file that is synchronized >
<! by MyEclipse Hibernate tool integration >
<hibernateconfiguration>
<sessionfactory>
<! properties >
<property name=connectiondatasource>java:comp/env/jdbc/test</property>
<property name=show_sql>true</property>
<property name=dialect>netsfhibernatedialectMySQLDialect</property>
<! mapping files >
<mapping resource=com/netease/wireless/groupsms/hbnt/po/cathbmxml/>
</sessionfactory>
</hibernateconfiguration>
四测试servlet
//Session生成/关闭
