用Java语言编写处理Oracle数据库设备运行数据分类存储的代码，采用ssm架构

以下是一个简单的示例Java代码，使用SSM框架连接Oracle数据库并进行数据分类存储操作。

1. 首先，需要在pom.xml文件中添加相关依赖：

<dependencies>
    <!-- Spring -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>5.2.9.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.2.9.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>5.2.9.RELEASE</version>
    </dependency>
    <!-- MyBatis -->
    <dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis</artifactId>
        <version>3.5.5</version>
    </dependency>
    <dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis-spring</artifactId>
        <version>2.0.5</version>
    </dependency>
    <!-- Oracle JDBC -->
    <dependency>
        <groupId>com.oracle.database.jdbc</groupId>
        <artifactId>ojdbc8</artifactId>
        <version>19.8.0.0</version>
    </dependency>
</dependencies>

2. 在applicationContext.xml文件中添加相关配置，包括数据源、MyBatis配置和事务管理器：

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
    <property name="url" value="jdbc:oracle:thin:@localhost:1521:ORCL"/>
    <property name="username" value="your_username"/>
    <property name="password" value="your_password"/>
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>

<tx:annotation-driven transaction-manager="transactionManager"/>

3. 创建一个数据模型类，用于存储设备运行数据：

public class DeviceData {
    private int id;
    private String deviceName;
    private String dataTime;
    private double dataValue;

    // Getters and setters
}

4. 创建一个数据访问类，使用MyBatis进行数据库操作：

@Repository
public class DeviceDataDAO {
    @Autowired
    private SqlSessionFactory sqlSessionFactory;

    @Transactional
    public void insertDeviceData(DeviceData deviceData) {
        try (SqlSession sqlSession = sqlSessionFactory.openSession()) {
            sqlSession.insert("DeviceDataMapper.insertDeviceData", deviceData);
        }
    }

    public List<DeviceData> getDeviceDataByDeviceName(String deviceName) {
        try (SqlSession sqlSession = sqlSessionFactory.openSession()) {
            return sqlSession.selectList("DeviceDataMapper.getDeviceDataByDeviceName", deviceName);
        }
    }
}

5. 创建一个控制器类，处理请求并调用数据访问类进行数据库操作：

@Controller
public class DeviceDataController {
    @Autowired
    private DeviceDataDAO deviceDataDAO;

    @RequestMapping(value = "/insertDeviceData", method = RequestMethod.POST)
    @ResponseBody
    public String insertDeviceData(@RequestBody DeviceData deviceData) {
        deviceDataDAO.insertDeviceData(deviceData);
        return "success";
    }

    @RequestMapping(value = "/getDeviceDataByDeviceName", method = RequestMethod.GET)
    @ResponseBody
    public List<DeviceData> getDeviceDataByDeviceName(@RequestParam String deviceName) {
        return deviceDataDAO.getDeviceDataByDeviceName(deviceName);
    }
}

6. 最后，在mybatis-config.xml文件中添加相关映射配置：

<mappers>
    <mapper resource="mapper/DeviceDataMapper.xml"/>
</mappers>

7. 创建DeviceDataMapper.xml文件，添加SQL语句和映射配置：

<mapper namespace="DeviceDataMapper">
    <insert id="insertDeviceData" parameterType="com.example.DeviceData">
        insert into device_data (device_name, data_time, data_value)
        values (#{deviceName}, #{dataTime}, #{dataValue})
    </insert>

    <select id="getDeviceDataByDeviceName" resultType="com.example.DeviceData">
        select * from device_data
        where device_name = #{deviceName}
        order by data_time desc
    </select>
</mapper>

以上就是一个简单的SSM架构的Java代码示例，用于处理Oracle数据库设备运行数据分类存储。
