How to implement map traversal in velocity

Editor to share with you how to achieve map traversal in velocity, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

List traversal in velocity is relatively simple, so map traversal, here are two kinds of velocity Map

Ergodic method,

Two kinds of velocity traversing map

Java Code:

Soft attribute: quantity num, name name

Soft soft = new Soft ("3", "iqiyi app")

SoftTypeMap {1,soft}

Front-end code:

1:

# foreach ($item in $! softTypeMap.entrySet ())

$! {item.key}. $! {item.value.name} / 1. Iqiyi app

# end

2:

# foreach ($item in $! softTypeMap.keySet ())

$! {item}. $! {softTypeMap.get ($item) .name} / / 1. Iqiyi app

. # end
