Question

我正在调用存储过程。这是我的Spring设置和类

Spring setup

@Configuration
@PropertySource(value = { "classpath:database/jdbc.properties" })
@EnableTransactionManagement
public class PersistenceConfig {

    @Autowired
    private Environment env;

    @Bean(destroyMethod = "close")
     public DataSource mySqlDataSource() {
         BasicDataSource dataSource = new BasicDataSource();
         dataSource.setDriverClassName(env.getProperty("jdbc.mysql.driverClassName"));
         ...
         return dataSource;
     }

     @Bean
     public JdbcTemplate mySqlJdbcTemplate() {
         JdbcTemplate jdbcTemplate = new JdbcTemplate(mySqlDataSource());
         return jdbcTemplate;
     }
}

Dao班

@Repository
public class MySQLCourseRenewalDaoImpl implements MySQLCourseRenewalDao {

    @Inject
    private JdbcTemplate mySqlJdbcTemplate;

    @Override
    public void callStoredProcedure(String storedProcedureName, Map<String, Object> inParamMap) throws Exception {

        SimpleJdbcCall simpleJdbcCall = new SimpleJdbcCall(mySqlJdbcTemplate).withProcedureName(storedProcedureName);
        SqlParameterSource in = new MapSqlParameterSource(inParamMap);
        Map<String, Object> simpleJdbcCallResult = simpleJdbcCall.execute(in);
    }
}

在inParamMap我正在输入一个像

这样的参数

LocalDateTime iUserCourseCourseCompletionDate = userCourse.getCourseCompletionDate();
inParamMap.put("iUserCourseCourseCompletionDate", Timestamp.valueOf(iUserCourseCourseCompletionDate));

如果我删除Timestamp.valueOf并仅使用inParamMap.put("iUserCourseCourseCompletionDate",iUserCourseCourseCompletionDate);。然后当存储过程运行时，我得到以下异常

CallableStatementCallback; SQL [{call usp_processCourseRenewal(?, ?, ?, )}]; Cannot convert class java.time.LocalDateTime to SQL type requested due to java.lang.ClassCastException - java.time.LocalDateTime cannot be cast to java.util.Date; nested exception is java.sql.SQLException: Cannot convert class java.time.LocalDateTime to SQL type requested due to java.lang.ClassCastException - java.time.LocalDateTime cannot be cast to java.util.Date

使用TimeStamp和java.util.Date存储过程可以正常工作。是否有任何方式存储过程调用也适用于Java8日期时间API。

我正在使用spring 4.2.2

由于

使用SimpleJdbcCall调用StoredProcedure如果参数类型为LocalDateTime，则抛出异常类抛出异常
