# Liquor for java

Java 动态编译小工具。(此工具可兼容 jar in jar 的情况)


本工具的代码主要源自 arthas。相关的知识点比较冷门，甚是珍贵，但也只能用在合适的场景上（切不可滥用）。为了复用方便，特整理成一个小工具包进行长期维护。


零依赖，发布包仅 24KB。

### 演示


```xml
<dependency>
    <groupId>org.noear</groupId>
    <artifactId>liquor</artifactId>
    <version>1.1.1</version>
</dependency>
```

```java
public class DemoApp {
    public static void main(String[] args) throws Exception{
        String className = "HelloWorld";
        String classCode = "public class HelloWorld { " +
                "   public static void helloWorld() { " +
                "       System.out.println(\"Hello, world!\"); " +
                "   } " +
                "}";

        DynamicCompiler compiler = new DynamicCompiler();
        //添加源码（可多个）并 构建
        compiler.addSource(className, classCode).build();

        Class<?> clazz = compiler.getClassLoader().loadClass(className);
        clazz.getMethod("helloWorld").invoke(null);
    }
}
```
