Spring EL supports most of the standard mathematical, logical or relational operators. For example,

• Relational operators – equal (==, eq), not equal (!=, ne), less than (<, lt), less than or equal (<= , le), greater than (>, gt), and greater than or equal (>=, ge).
• Logical operators – and, or, and not (!).
• Mathematical operators – addition (+), Subtraction (-), Multiplication (*), division (/), modulus (%) and exponential power (^).

Spring EL in Annotation

This example demonstrates the use of operators in SpEL.

package com.mkyong.core;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component("customerBean")
public class Customer { 
    //Relational operators 
    @Value("#{1 == 1}") //true 
    private boolean testEqual; 
    @Value("#{1 != 1}") //false 
    private boolean testNotEqual; 
   @Value("#{1 < 1}") //false 
    private boolean testLessThan; 
    @Value("#{1 <= 1}") //true 
    private boolean testLessThanOrEqual; 
    @Value("#{1 > 1}") //false 
    private boolean testGreaterThan; 
    @Value("#{1 >= 1}") //true 
    private boolean testGreaterThanOrEqual; 
    //Logical operators , numberBean.no == 999 
    @Value("#{numberBean.no == 999 and numberBean.no < 900}") //false 
    private boolean testAnd; 
    @Value("#{numberBean.no == 999 or numberBean.no < 900}") //true 
    private boolean testOr; 
    @Value("#{!(numberBean.no == 999)}") //false 
    private boolean testNot; 
    //Mathematical operators @Value("#{1 + 1}") //2.0 
    private double testAdd; 
    @Value("#{'1' + '@' + '1'}") //1@1 
    private String testAddString; 
    @Value("#{1 - 1}") //0.0 
    private double testSubtraction; 
    @Value("#{1 * 1}") //1.0 
    private double testMultiplication; 
    @Value("#{10 / 2}") //5.0 
    private double testDivision; 
    @Value("#{10 % 10}") //0.0 
    private double testModulus ; 
    @Value("#{2 ^ 2}") //4.0 
    private double testExponentialPower; 
    @Override 
    public String toString() { 
        return "Customer [testEqual=" + testEqual + ", testNotEqual=" + testNotEqual + ", testLessThan=" + testLessThan + ", testLessThanOrEqual=" + testLessThanOrEqual + ", testGreaterThan=" + testGreaterThan + ", testGreaterThanOrEqual=" + testGreaterThanOrEqual + ", testAnd=" + testAnd + ", testOr=" + testOr + ", testNot=" + testNot + ", testAdd=" + testAdd + ", testAddString=" + testAddString + ", testSubtraction=" + testSubtraction + ", testMultiplication=" + testMultiplication + ", testDivision=" + testDivision + ", testModulus=" + testModulus + ", testExponentialPower=" + testExponentialPower + "]"; 
    } 
}

package com.mkyong.core;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component("numberBean")
public class Number { 
    @Value("999") 
    private int no; 
    public int getNo() { 
        return no; 
    } 
    public void setNo(int no) { 
        this.no = no; 
    }
}

*Run it *

Customer obj = (Customer) context.getBean("customerBean"); 
System.out.println(obj);

Output
Customer [ testEqual=true, testNotEqual=false, testLessThan=false, testLessThanOrEqual=true, testGreaterThan=false, testGreaterThanOrEqual=true, testAnd=false, testOr=true, testNot=false, testAdd=2.0, testAddString=1@1, testSubtraction=0.0, testMultiplication=1.0, testDivision=5.0, testModulus=0.0, testExponentialPower=4.0]

Spring EL in XML
See equivalent version in bean definition XML file. In XML, symbol like "less than" is always not support, instead, you should use the textual equivalents shown above, for example, ('<' = 'lt') and ('<=' = 'le').
