Lombok

I am experimenting in combining Jackson and Lombok. Those are my classes: package testelombok; import com.fasterxml.jackson.annotation.JsonCreator; import com.fasterxml.jackson.annotation.JsonProperty; import lombok.AllArgsConstructor; import lombok.Value; import lombok.experimental.Wither; @Value @Wither @AllArgsConstructor(onConstructor=@__(@JsonCreator)) public class TestFoo { @JsonProperty("xoom") private String x; private int z; } package testelombok; import com.fasterxml.jackson.databind.ObjectMapper; import com.xebia.jacksonlombok.JacksonLombokAnnotationIntrospector; import java.io

优雅的Java工具库Lombok 最近在公司的项目中看到了对于Lombok的应用，通过@Data注解标注POJO，省略了大量的getter/setter代码，原先冗长的POJO在瘦身之后直接变得干净、清爽，程序员再也不需要去关注那些长长的方法，只需要集中注意力于字段field之中 Lombok简介 Lombok是一个非常实用的Java工具库，有效地简化Java代码的冗长。它通过注解如@Data可以直接为Java bean在编译期动态地生成字段的getter/setter方法，使用注解@NoArgsConstructor 和@AllArgsConstructor 为Java bean添加无参构造器和有参构造器，甚至可以在Java代码中使用val和var声明一个动态变量，而无需再指定具体的变量类型，区别只是val声明的变量为final。Lombok还提供了delombok供生成Javadoc，delombok在运行时会将注解@Data转换成getter/setter方法，然后移除@Data注解，如果哪天不再需要Lombok，也只需要简单运行delombok即可。Lombok的构建支持maven和gradle，同时eclipse、myeclipse和idea等主流IDE也都和lombok兼容，所以可以放心大胆地使用Lombok，不用担心IDE的编译检查问题。 Lombok栗子

项目地址 ： http://code.google.com/p/lombok-intellij-plugin/#IntelliJ_Idea_plugin_project_for_project. 介绍： Provides support for lombok annotations to write great java code with IntelliJ Idea. With this plugin your IntelliJ can recognize all of generated getters, setters and some other things from lombok project, so that you get code completion and are able to work without errors stating the methods don't exists. New version (0.5) released on 22.08.2012 Fifth version of plugin released. Now with support for IntelliJ 9, 10, 11, and 12! Install it automatically from IntelliJ Idea plugin repository.

I'm trying to retrieve the description of a few Java Beans from an XML file. I'd like to annotate them with @Data from project lombok to automatically include constructor, equals, hashCode, getters, setters and toString. I'd like to compile them in memory, generate a few instances (with data from the same XML file) and add them to Drools to eventually do some reasoning on that data. Unfortunately, I cannot compile those classes and so I am asking for your help! The following code shows how to programmatically compile Java classes in memory: package example; import java.util.ArrayList; import

Can someone explain this code? public class SneakyThrow { public static void sneakyThrow(Throwable ex) { SneakyThrow.<RuntimeException>sneakyThrowInner(ex); } private static <T extends Throwable> T sneakyThrowInner(Throwable ex) throws T { throw (T) ex; } public static void main(String[] args) { SneakyThrow.sneakyThrow(new Exception()); } } It may seems strange, but this doesn't produce a cast exception, and permits to throw a checked exception without having to declare it in the signature, or to wrap it in an unchecked exception. Notice that neither sneakyThrow(...) or the main are declaring
