基于javaweb+mysql的ssm流浪动物收养系统(java+ssm+jsp+jquery+mysql)
这是一个基于JavaWeb、SSM框架和MySQL数据库的流浪动物收养系统。由于代码量较大,我将提供部分核心代码和配置文件的示例。
配置文件applicationContext.xml的一部分:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- 数据库连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<!-- 其他配置 -->
</bean>
<!-- 配置SqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:mybatis-config.xml"/>
<property name="mapperLocations" value="classpath:mappers/*.xml"/>
</bean>
<!-- 配置扫描Mapper接口的包,动态生成代理对象 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.yourpackage.mapper"/>
</bean>
<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 开启注解事务 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
Service层示例代码:
@Service
public class AnimalServiceImpl implements AnimalService {
@Autowired
private AnimalMapper animalMapper;
@Override
@Transactional
public void adoptAnimal(AdoptRequest request) {
// 业务逻辑,例如保存收养信息等
animalMapper.updateStatus(request.getAniId(), "adopted");
}
}
Controller层示例代码:
@Controller
public class AnimalController {
@Autowired
private AnimalService animalService;
@RequestMapping("/adopt")
@ResponseBody
public String adoptAnimal(AdoptRequest request) {
try {
animalService.adoptAnimal(request);
return "success";
} catch (Exception e) {
return "error";
}
}
}
以上代码仅为示例,实际系统中会有更多的细节和功能。这个系统的核心功能是展示如何使用S
