springboot整合mybatisplus调用Oracle存储过程代码怎么写

下面是一个简单的示例代码，演示了如何在Spring Boot中使用Mybatis Plus框架调用Oracle存储过程。

1. 首先，需要在pom.xml文件中添加MyBatis Plus和Oracle JDBC驱动程序的依赖项：

<dependencies>
    <!-- MyBatis Plus -->
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <version>3.3.2</version>
    </dependency>

    <!-- Oracle JDBC driver -->
    <dependency>
        <groupId>com.oracle.database.jdbc</groupId>
        <artifactId>ojdbc8</artifactId>
        <version>19.3.0.0</version>
    </dependency>
</dependencies>

2. 编写Mybatis Plus配置类，配置Oracle数据源，并添加对应的Mapper扫描路径：

@Configuration
@MapperScan("com.example.demo.mapper")
public class MybatisPlusConfig {
    @Bean
    public DataSource dataSource() {
        // TODO: replace with your own Oracle connection information
        String url = "jdbc:oracle:thin:@localhost:1521:orcl";
        String username = "your_username";
        String password = "your_password";
        return new DriverManagerDataSource(url, username, password);
    }

    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
        MybatisSqlSessionFactoryBean factoryBean = new MybatisSqlSessionFactoryBean();
        factoryBean.setDataSource(dataSource());
        factoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:/mapper/*.xml"));
        return factoryBean.getObject();
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        return new DataSourceTransactionManager(dataSource());
    }
}

3. 编写存储过程的Mapper接口：

@Mapper
public interface MyStoredProcedureMapper {
    @Options(statementType = StatementType.CALLABLE)
    @Select("{call your_procedure_name(#{inputParam1, mode=IN}, #{inputParam2, mode=IN}, #{outputParam1, mode=OUT, jdbcType=NUMERIC}, #{outputParam2, mode=OUT, jdbcType=VARCHAR})}")
    void callMyStoredProcedure(@Param("inputParam1") String inputParam1, @Param("inputParam2") String inputParam2, @Param("outputParam1") Integer outputParam1, @Param("outputParam2") String outputParam2);
}

注意，这里的@Select注解中使用了Oracle的存储过程调用语法，其中包含了输入参数、输出参数的定义，需要根据实际情况进行修改。

4. 在业务逻辑中调用存储过程：

@Service
public class MyService {
    @Autowired
    private MyStoredProcedureMapper myStoredProcedureMapper;

    public void callMyStoredProcedure() {
        String inputParam1 = "your_input_param1";
        String inputParam2 = "your_input_param2";
        Integer outputParam1 = null;
        String outputParam2 = null;
        myStoredProcedureMapper.callMyStoredProcedure(inputParam1, inputParam2, outputParam1, outputParam2);
        // TODO: use the output parameters returned by the stored procedure
    }
}

注意，在调用存储过程时，需要传入输入参数，并且需要定义输出参数的变量，以便在存储过程执行完成后读取输出参数的值。
