今天用Java Stream写了这样一段代码，本意是合并两个list，并去重，但是出现无法启动问题

1、代码

supplierNames = Stream.concat(supplierNames.stream(), supplierNameTemp.stream())

                        .distinct().collect(Collectors.toList());

2、启动出现如下问题

Caused by: java.lang.IllegalArgumentException: INVOKESPECIAL/STATIC on interfaces require ASM 5

at org.springframework.asm.MethodVisitor.visitMethodInsn(Unknown Source)

at org.springframework.asm.ClassReader.a(Unknown Source)

... 37 more

3、排查原因

低版本（例如3.2.9）的spring不支持调用接口中的static方法，例如

Comparator.comparingInt

Function.identity

查看我的spring的pom版本以及Stream.concat具体定义信息，正是接口中static方法

spring版本查看

Stream.concat定义

4、问题解决

修改成笨笨的方式，启动无问题

supplierNames.addAll(supplierNameTemp);

supplierNames = supplierNames.stream().distinct().collect(Collectors.toList());
