-# Spring Expression Language
-
-The Spring Expression Language (SpEL) is a powerful expression language that supports querying and manipulating an object graph at runtime.
-
-Refer to the [4.2.x Spring Documentation](https://docs.spring.io/spring/docs/4.2.x/spring-framework-reference/html/expressions.html)
-for details.
-
-The following example shows how to execute a simple SpEL script with variables:
-```java
-try {
-    ScriptEngineManager manager = new ScriptEngineManager();
-    ScriptEngine engine = manager.getEngineByName("spel");
-
-    engine.put("inputA", 2);
-    engine.put("inputB", 3);
-    engine.put("output", 0);
-
-    String script = "" +
-            "#output = #inputA + #inputB";
-
-    Object result = engine.eval(script);
-    System.out.println("Result: " + result);
-
-    Object output = engine.get("output");
-    System.out.println("Output Variable: " + output);
-} catch (ScriptException e) {
-    e.printStackTrace();
-}
-```
-
-The console output shows that the `output` variable was modified by the script:
-```console
-Result: 5
-Output Variable: 5
-```
-
-Since SpEL has the concept of a root object that is passed into expression
-the `SpringExpressionScriptEngine` provides a special variable `ROOT`.
-
-```java
-public class Person {
-    public String name;
-    public int birthYear;
-
-    @Override
-    public String toString() {
-        return "Person{name=" + name + ", birthYear=" + birthYear + "}";
-    }
-}
-```
-
-```java
-try {
-    ScriptEngineManager manager = new ScriptEngineManager();
-    ScriptEngine engine = manager.getEngineByName("spel");
-
-    Person person = new Person();
-    person.name = "Eric";
-    person.birthYear = 1967;
-    engine.put(SpringExpressionScriptEngine.ROOT, person);
-
-    String script = "" +
-            "name+birthYear";
-
-    Object result = engine.eval(script);
-    System.out.println("Result: " + result);
-} catch (ScriptException e) {
-    e.printStackTrace();
-}
-```
-
-```console
-Result: Eric1967
-```
