java--dom读取xml文件

 public Map readXml() {

dictionaries.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<dictionaries>
    <dictionary name="项目类型" value="project.types" />
    <dictionary name="项目状态" value="project.statuses" />
    <dictionary name="任务阶段" value="task.stages" />
    <dictionary name="任务状态" value="task.statuses" />
    <dictionary name="发生几率" value="risk.probability" />
    <dictionary name="危险程度" value="risk.harm" />
    <dictionary name="风险状态" value="risk.status" />
    <dictionary name="预案类别" value="risk.type" />
    <dictionary name="合同类型" value="contract.type" />
