EMF保存CDATA

    /**
     * <!-- begin-user-doc -->
     * <!-- end-user-doc -->
     * @generated NOT
     */
    public String getCDATA() {
        String str = (String)getMixed().get(PagePackage.Literals.XXX, true);
        return str==null?null:str.substring("<![CDATA[".length(), str.indexOf("]]>"));
    }

    /**
     * <!-- begin-user-doc -->
     * <!-- end-user-doc -->
     * @generated NOT
     */
    public void setCDATA(String newStr) {
        newStr = "<![CDATA[" +newStr + "]]>";
        ((FeatureMap.Internal)getMixed()).set(PagePackage.Literals.XXX, newStr);
    }

需要把保存的属性在ecore中设为featureMap类型或者在schema中类型多设置mixed="true"

别忘了方法上加上generated not注解

保存的时候添加escape选项map

Map<String, Object> map = new HashMap<String, Object>();
map.put(XMLResource.OPTION_SKIP_ESCAPE, Boolean.TRUE);
        
try {
     // 保存文件
     resource.save(map);
    } catch (IOException e) {
      e.printStackTrace();
    }
