How to run code after constructor in a Lombok builder

由 核能气质少年 提交于 2020-01-01 02:30:09
问题 I have a class that I want to use Lombok.Builder and I need pre-process of some parameters. Something like this: @Builder public class Foo { public String val1; public int val2; public List<String> listValues; public void init(){ // do some checks with the values. } } normally I would just call init() on a NoArg constructor, but with the generated builder I'm unable to do so. Is there a way for this init be called by the generated builder? For example build() would generate a code like:

Does Project Lombok support Java 9?

问题 I have used Lombok in my project, but my colleague do not agree to use it, and his reason is （from controversy of lombok documents） Both of these pieces of Project Lombok make use of non-public APIs to accomplish their sorcery. This means that there is a risk that Project Lombok will be broken with subsequent IDE or JDK releases. But it's a very old document written in 2010, maybe now it has resolved the problem, so I want to know if Lombok will support Java 9 and does it still use the non

SpringBoot基础教程2-1-3 异常处理规范

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 1. 概述 异常处理 ，在平时业务处理中不可避免；但是，阅读代码最头疼的就是看到一堆 try-catch 语句，业务逻辑参杂其中，极难维护；那要怎样优雅的处理异常呢？请耐心阅读全文。 2. 不负责任的处理异常 直接抛出异常或遗漏未捕获异常，会怎样？Spring Boot提供了一个默认的映射：/error，当处理中抛出异常之后，会转到该请求中处理，并且该请求有一个全局的错误页面用来展示异常内容 @RestController public class BadExceptionController { @GetMapping("/bad") public String bad(){ // todo 业务逻辑 Object object = null; // 模拟空指针异常 object.toString(); return "success"; } } 上述代码极不负责，看看测试结果 当调用者看到这个结果，估计一脸懵 3. 丑陋的异常处理 常见的异常处理，在 try-catch 块中，手动封装返回对应结果；该方法相比上面，虽然封装了异常，但是异常处理逻辑，嵌在业务逻辑中，当要修改业务逻辑时，也不可避免的新增对于异常处理逻辑，耦合度非常高 @RestController public class
