# kotlin-backend-tool-library
A kotlin backend development tool library,mainly includes common kotlin extensions for daily projects
# Easily add kotlin to existing Java projects
# 轻松将kotlin加入现有的java项目
### kotlin是java生态中最好用的库！！！
Spring Initializr默认生成的kotlin项目只能在kotlin代码中调用java。不能互相调用。
由于kotlin和java的良好互操作性，可以在任何项目中加入kotlin代码，不影响现有的java代码。
# 如何使用？
## 1.引入maven parent
配置kotlin所有插件，还包括格式化插件，findBug插件等常用插件只需要将
```xml
org.springframework.boot
spring-boot-starter-parent
2.7.0
```
替换成：
```xml
com.github.jchanghong
kbtool-parent
2.7.0
```
## 2.加入kbtool-lib依赖(如果只是想增加kotlin插件配置，不需要引入)
通过加入如下依赖,就可以把后端常用库全部引入，
比如guava，hutool，common系列，spring-mvc,validation,json常用库，http，retry常用库等等
```xml
com.github.jchanghong
kbtool-lib
2.7.0
```
并将工作中常用的工具类，独立出来，方便多项目引入，比如下面这些代码（会持续更新）：
```kotlin
val date = "2022-05-05 00:00:00".toDateJdk7OrNull()
println(date.toStrOrNow())
println(date.toLocalDateTime().toStrOrNow())
println(date.toJsonStr())
println("hello".toUnderlineCase())
println("hello".upperFirst())
println("hello".toCamelCase())
RetryHelper.submitByRetry4Times(aCallable)
RetryHelper.submitByRetryNTimes(aCallable)
HttpHelper.postJsonStringSyn("https://","{}")
val abean="{}".jsonToObject()
```
