Java工具

1. Groovy shell

可以在Java代码里执行脚本，可以将Java方法配置在文件里

依赖

<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-all</artifactId>
<version>2.1.6</version>
</dependency>

Java代码

public class GroovyShellTest {
    private static GroovyShell groovyShell = null;
    private static Script script = null;

    static {
        CompilerConfiguration config = new CompilerConfiguration();
        config.setScriptBaseClass(MyScript.class.getName());
        groovyShell = new GroovyShell(config);
    }

    public static String getScriptText(){
        return "getName(name,age,height)";
    }

    public static void main(String[] args){
        Map<String, Object> binding = new HashMap<String, Object>();
        binding.put("name", "Alex");
        binding.put("age", 27);
        binding.put("height", 172.06);
        script = groovyShell.parse(getScriptText());
        script.setBinding(new Binding(binding));
        Object val = script.run();
        System.out.println(val);
    }
}

public class MyScript extends Script{
    @Override
    public Object run() {
        return null;
    }

    public static String getName(String name, int age, double height){
        return "Name is " + name + "; age is " + age + "; height is " + height;
    }
}

2.JAXB

Java对象和XML之间转换

3.数据序列化

Google Protobuf
