Error message:

The incoming Table Format Data Stream (TDS) Remote Procedure Call (RPC) protocol stream is incorrect. Too many parameters were provided in this RPC request. The maximum should be 2100

Error analysis:

Due to too many SQL statement parameters spliced by mybatis

Solution:

Batch processing without mybatis

① Configuration file   applicationContext-mybatis.xml

　　<!-- Solving mybatis batch insert -->
    <bean class="org.mybatis.spring.SqlSessionTemplate" id="sqlSession">
        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory" />
        <constructor-arg name="executorType" value="BATCH" />
    </bean>

②service import

　　　　@Autowired
	private SqlSessionTemplate sst;

③ The self encapsulated method was used in the service for batch insert

	public Boolean insert(List<PDA_JWL_INTERFACE_H> inList,String zyh){
		// Get a new session with mode BATCH and auto-commit set to false
		// If auto-commit is set to true, it will not be possible to control the number of commits and will instead be submitted uniformly at the end, which may lead to a memory overflow
		SqlSession session = sst.getSqlSessionFactory().openSession(ExecutorType.BATCH,false);
		moMapper= session.getMapper(MOMapper.class);
		Map<String,Object> cc = new HashMap<>();
		
		try {
			for (PDA_JWL_INTERFACE_H in : inList) {
				moMapper.insert(in);
			}
			cc.put("zyh", zyh);
			moMapper.call(cc);
			session.commit();
			//Clearing the cache to prevent overflow
			session.clearCache();
			return true;
		} catch (Exception e) {
			session.rollback();
			return false;
		} finally {
			session.close();
		}
