velocity获取list，map以及list套map中数据

1.velocity 获取list 中的值

VelocityEngine veloEngine = new VelocityEngine();


Template template = veloEngine.getTemplate(xmlPath, "UTF-8");
VelocityContext velocityContext = new VelocityContext();
List<Object> list = new ArrayList<Object>();
list.add("1");
list.add("2");


velocityContext.put("list", list);

  

  XML中写法为 

   #foreach($data in $list)     
<risk> 
<age>$!data </age> @$!其中！代表非空时取值，避免值为空时显示为data
</risk>
#end

   2.velocity 获取map 中的值

  Map<String,Object> map = new HashMap<String,Object>();
map.put("age", "11");
map.put("sex","男");

velocityContext.put("data", map);

XML中写法为 

  <age>$!data.age</age>
  <sex>$!data.sex</sex>
  3.velocity 获取list套map 中的值


List<Object> list = new ArrayList<Object>();
Map<String, Object> map2 = new HashMap<String, Object>();
map2.put("age", "11");
Map<String, Object> map3 = new HashMap<String, Object>();
map3.put("age", "22");
map3.put("bname", "bname");
list.add(map2);
list.add(map3);

Map<String, Object> map = new HashMap<String, Object>();
map.put("list", list);
velocityContext.put("data", map);


XML中写法为


  
   #foreach ($lis in ${data})  @第一次循环获取list
   #foreach( $aa in $lis)    @然后将lis循环获取变量 
<risk>

<age>$!aa.age </age>
<age>$!aa.bname </age>
</risk>
#end
   #end
