kotlin 学习 三 maven 集成+java 互调用
项目基于idea 生成，主要是说明使用方法
环境准备
- 项目结构
- main.kt
fun main(args: Array<String>) {
val user: User = User();
user.age=333;
user.name="dalong"
println("this is my user ${user.name} ${user.age}")
}
- User.java
/**
* @author dalong
*/
public class User {
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
- pom.xml

构建&&运行
- 构建
maven clean package
- 运行
java -jar target/consoleApp-1.0-SNAPSHOT-jar-with-dependencies.jar
效果 
说明
以上是一个简单的试用，实际互调用部分还是应该多看看官方文档
