java – JdbcBatchItemWriter – 关键字“ON”附近的语法错误

"INSERT INTO USER (username,address) VALUES (:username,:address) ON DUPLICATE KEY UPDATE username = username"

但我得到以下例外

org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [{my_query_above}]; nested exception is java.sql.SQLException: Incorrect syntax near the keyword 'ON'.

查询运行正常,没有ON条件.知道为什么会失败吗？

UPDATE

这是写配置

@Bean
public ItemWriter<User> userWriter(DataSource dataSource) throws SQLException {
    JdbcBatchItemWriter<User> userWriter = new JdbcBatchItemWriter<User>();
    userWriter.setItemSqlParameterSourceProvider(new BeanPropertyItemSqlParameterSourceProvider<StagingProcess>());
    userWriter.setSql(QueryUtil.QUERY_INSERT_PROCESS);
    userWriter.setDataSource(sqlServerDataSource());
    return userWriter;
}

@Primary
@Bean(name="sqlserverDS")
public static DataSource sqlServerDataSource() throws SQLException {
    final DriverManagerDataSource sqlServerDataSource = new DriverManagerDataSource();      sqlServerDataSource.setDriverClassName("net.sourceforge.jtds.jdbc.Driver");
    sqlServerDataSource.setUrl("jdbc:jtds:sqlserver://myHost:8080/myDB");
    sqlServerDataSource.setUsername("user");
    sqlServerDataSource.setPassword("password");
    return sqlServerDataSource;
}

更多的堆栈跟踪
