I am using java7, spring 3 and mybatis

Pom.xml

<org.mybatis-version>3.2.8</org.mybatis-version>
<org.mybatis-spring-version>1.2.2</org.mybatis-spring-version>

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>${org.mybatis-version}</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>${org.mybatis-spring-version}</version>
</dependency>
 

While using annotation based Select i came across with strange issue where below mentioned code was throwing exception due to use of < (Less then) while > (greater then) works as expected.

<script>
SELECT * FROM STUDENT
WHERE DEPARTMENT_ID = #{depId}
<if test=‘joiningDate != null‘> AND STUDENT_ID <= #{joiningDate} </if>
</script>
 

After googling for a while i find out this issue reported below.

Above issue can be fixed by replacing < (less then) with < as shown below.

<script>
SELECT * FROM STUDENT
WHERE DEPARTMENT_ID = #{depId}
<if test=‘joiningDate != null‘> AND STUDENT_ID &lt;= #{joiningDate} </if>
</script>
 

I have also came across of suggestion for using using CDATA or ^ in respected scenarios which i haven‘t given try yet.
