MultiActionController弹簧MVC 5.2.6

如何解决MultiActionController弹簧MVC 5.2.6

我们正在将应用程序从Spring 3.x迁移到Spring 5。

但是有一个问题，使用了一些MultiActionController类。

请让我知道我们如何在Spring mvc 5中实现相同的目标。

我们正在使用xml配置。

调度程序servlet。 Xml

    open class Point(val x: Int,val y: Int,val z: Int) {
        override fun toString(): String = 
            "Point(${this.x},${this.y},${this.z})"
    }

    data class OptPoint(val point: Point,val additional: Int): 
        Point(point.x,point.y,point.z) {
        
        override fun toString(): String = 
            "OptPoint(${this.point},${this.additional})"
            
        fun optimize(): Point {
            return Point(this.x,this.y,this.z)
        }
    }

    open class Track(private val points: Iterable<Point>): Iterable<Point> {
        
        override operator fun iterator(): Iterator<Point> {
            return this.points.iterator()
        }
        
        override fun toString(): String = 
            "Track(${this.points})"
    }

    data class OptTrack(private val points: Iterable<OptPoint>): Track(listOf()) {
        
        override operator fun iterator(): Iterator<Point> {
            return this.points.iterator()
        }
        
        fun optimize(): Track {
            return Track(this.points.map{ it.optimize() })
        }
    }

    fun main(args: Array<String>) {
        val track: Track = OptTrack(listOf(
                 OptPoint(Point(1,2,3),4))).optimize()
        println(track)        
        // Track([Point(1,3)])
        val other: Track = OptTrack(listOf(OptPoint(Point(1,4)))
        println(other)
        // OptTrack(points=[OptPoint(Point(1,4)])
    }
