Abnormal record, I have encountered similar problems, but because I have not recorded, I have been investigated for nearly two hours, I remember to remember! ! !

See an abnormal description

org.springframework.jdbc.UncategorizedSQLException: 
### Error querying database.  Cause: java.sql.SQLException: sql injection violation, syntax error: TODO QUES : SELECT nvl(QBXSSR,0) from GS_SB_SBXX t

Abnormal code segment in Mybatis XML

	<select id="getTaxZzsXSSR" parameterType="map" resultType="BigDecimal">
		SELECT nvl(QBXSSR,0) from GS_SB_SBXX t
		WHERE t.result_id=#{resultId} AND t.ZSXM_DM='10101'
		AND trunc(t.SSSQZ,'mm') BETWEEN add_months(TO_DATE(#{zzsMaxDate},'yyyy-mm-dd'),-#{somendxj})  
					AND add_months(TO_DATE(#{zzsMaxDate},'yyyy-mm-dd'),-#{somendsj})
	</select>

 

This exception has been summarized, but there is a problem, then throw the entire SQL statement, not clearly explaining what problems and specific locations, will join SQL through DEBUG, and execute this script in PLSQL is not reported, So exclude the problem of statement, and determined that the ParameterType is correct, and finally determined as a connection method, into MAP MAP <string, object>, where Somendxj and Somendsj are int type, where the ginseng can not be # {xxx } The format is changed to $ {xxx}.

The solved code segment is

	<select id="getTaxZzsXSSR" parameterType="map" resultType="BigDecimal">
		SELECT nvl(QBXSSR,0) from GS_SB_SBXX t
		WHERE t.result_id=#{resultId} AND t.ZSXM_DM='10101'
		AND trunc(t.SSSQZ,'mm') BETWEEN add_months(TO_DATE(#{zzsMaxDate},'yyyy-mm-dd'),-${somendxj})  
					AND add_months(TO_DATE(#{zzsMaxDate},'yyyy-mm-dd'),-${somendsj})
	</select>
