传递参数和解析上述dsl的java方法代码
@Test
public void dynamicInnerDsl(){
Map conditions = new HashMap<String,Map<String,Object>>();
Map<String,Object> term = new HashMap<String, Object>();
term.put("terma","tavalue");
term.put("termb","tbvalue");
term.put("termc","tcvalue");
conditions.put("term",term);
Map params = new HashMap();
params.put("conditions",conditions);
params.put("size",1000);
//加载配置文件中的dsl信息，解析dsl语句dynamicInnerDsl
ESUtil esUtil = ESUtil.getInstance("esmapper/dsl.xml");
String parseResult = ESTemplateHelper.evalTemplate(esUtil,"dynamicInnerDsl",params);
//打印解析结果
System.out.println(parseResult);
}
运行上述代码打印出来的实际dsl
