今天写SQL遇到了这样的问题
org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [SELECT s.STUDENT_NAME,f.FACULTY_NAME,m.MAJOR_NAME,c.CLASS_NAME,g.GRADE_CODE,l.* FROM leave_info l LEFT JOIN student_info s ON s.STUDENT_KEY=l.STUDENT_KEY LEFT JOIN faculty_info f ON f.FACULTY_ID=s.FACULTY LEFT JOIN major_info m ON m.MAJOR_ID=s.MAJOR LEFT JOIN class_info c ON c.CLASS_ID=s.STUDENT_CLASS LEFT JOIN grade_info g ON c.GRADE_ID=g.GRADE_ID WHERE 1=1 AND s.SET_ID=1 AND s.FACULTY=402836e64f69e44e014f6f01203b000d]; nested exception is java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'f69e44e014f6f01203b000d' at line 1

然后一脸懵逼，试了好多方法，结果问题出在32位的uuid上面。在数据库解析的时候，把“402836e64f69e44e014f6f01203b000d”解析成了“402836e64 f69e44e014f6f01203b000d”中间多了一个空格，原因是mysql数据库执行的时候要在参数上加 '' 英文的单引号
if(StringUtils.isNotBlank(facultyId)){
sb.append(" AND s.FACULTY= '"+facultyId.trim()+"'");
}
if(StringUtils.isNotBlank(majorId)){
sb.append(" AND s.MAJOR= '"+majorId.trim()+"'");
}
if (StringUtils.isNotBlank(classId)){
sb.append(" AND s.STUDENT_CLASS= '"+classId.trim()+"'");
}在加上 '' 号之后运行马上正常了！
