2安寺、XStream支持CDATA標(biāo)簽
3、Retrofit 用Soap協(xié)議訪問WebService 詳解

實(shí)例

留著上一篇retrofit訪問webservice后首尼，最后到訪問成功挑庶，到需要解析CDATA數(shù)據(jù)為止，繼續(xù)下面的工作软能，先看下數(shù)據(jù)格式吧：

 * CDATA具體數(shù)據(jù)
 <![CDATA[
 <updatedata>
    <table>
        <name>table_xxx</name>
        <field>id, codeid, name, pid, remark, inputdate, modifydate, status, type_num</field>
        <values>
            <value>302|302|亞硝酸鹽|1|檢測項(xiàng)目|2016-08-24 10:58:51.0|null|C|null</value>
            ...
            <value>472|472|醬油氨基態(tài)氮|1|檢測項(xiàng)目|2016-08-24 10:58:51.0|null|C|null</value>
        </values>
    </table>-200

    <table>
        <name>table_yyy</name>
        <field>id, inputdate, modifydate, decision_basis, max_limit, min_limit, test_basis, unit, food_type, test_item</field>
        <values>
            ....
        </values>
    </table>
 </updatedata>
 ]]>

好吧迎捺。。查排。還需需要利器來解析凳枝，XStream來也（其他 SAX-xml，JSoup-html 應(yīng)該也可以）

1跋核、app 下的build.gradle岖瑰，添加依賴

    compile ('com.thoughtworks.xstream:xstream:1.4.7') {
        exclude group: 'xmlpull', module: 'xmlpull'
    }

2、xml的bean建立

2.1砂代、@XStreamAlias 根節(jié)點(diǎn)

2.2蹋订、@XStreamImplicit 子節(jié)點(diǎn)

2.3、解釋：（1）泊藕、子節(jié)點(diǎn)是值的話直接用 String xxSameAsElementName 來獲取 （2）辅辩、子節(jié)點(diǎn)里面還有子節(jié)點(diǎn)的話用bean來獲取，名字可取Element一樣的娃圆，不一樣要注解 （3）搏熄、子節(jié)點(diǎn)有N個相同的話用List<Bean>來獲取尾菇，且需要注解子節(jié)點(diǎn)

1没佑、第一層：updatedata是根節(jié)點(diǎn)唇撬，有子節(jié)點(diǎn)table且多個按脚，用list<bean>
2昔榴、第二層：table下都只有一個個單獨(dú)元素绽族，是值的話直接用string xxSameAsElment來獲取好了卖怜，有節(jié)點(diǎn)的話用bean
3、第三層：有N個相同數(shù)據(jù)础爬，標(biāo)注子節(jié)點(diǎn)甫贯，且用List<String>來獲取

@XStreamAlias("updatedata")//類注解(必須寫)，根節(jié)點(diǎn)
public class ZydUpdateDataBean {

    @XStreamImplicit(itemFieldName = "table")//節(jié)點(diǎn)注解(必須寫)看蚜，有N個用List
    private List<ZydTableBean> tables;

    public List<ZydTableBean> getTables() {
        return tables;
    }

    public void setTables(List<ZydTableBean> tables) {
        this.tables = tables;
    }

    //2 : 每個table下面可以看到有3個元素
    public static class ZydTableBean{
        String name;
        String field;
        ZydValues values;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getField() {
            return field;
        }

        public void setField(String field) {
            this.field = field;
        }

        public ZydValues getValues() {
            return values;
        }

        public void setValues(ZydValues values) {
            this.values = values;
        }

        //3
        public static class ZydValues{
            @XStreamImplicit(itemFieldName = "value")//節(jié)點(diǎn)注解(必須寫)
            private List<String> valueList;

            public List<String> getValueList() {
                return valueList;
            }

            public void setValueList(List<String> valueList) {
                this.valueList = valueList;
            }
        }
    }
}

3叫搁、支持CDATA的XStream工具編寫~~直接Copy來

public class XStreamUtil {
    public static String PREFIX_CDATA = "<![CDATA[";
    public static String SUFFIX_CDATA = "]]>";

    /**
     * 全部轉(zhuǎn)化
     */
    public static XStream initXStream() {
        return new XStream(new XppDriver() {
            @Override
            public HierarchicalStreamWriter createWriter(Writer out) {
                return new PrettyPrintWriter(out) {
                    protected void writeText(QuickWriter writer, String text) {
                        // if (text.startsWith(PREFIX_CDATA) &&
                        // text.endsWith(SUFFIX_CDATA)) {
                        writer.write(PREFIX_CDATA + text + SUFFIX_CDATA);
                        // } else {
                        // super.writeText(writer, text);
                        // }
                    }
                };
            }
        });
    }

    /**
     * 初始化XStream可支持某一字段可以加入CDATA標(biāo)簽,如果需要某一字段使用原文,就需要在String類型的text的頭加上
     * "<![CDATA["和結(jié)尾處加上"]]>"標(biāo)簽， 以供XStream輸出時進(jìn)行識別
     * @param isAddCDATA 是否支持CDATA標(biāo)簽
     */
    public static XStream initXStream(boolean isAddCDATA) {
        XStream xstream = null;
        if (isAddCDATA) {
            xstream = new XStream(new XppDriver() {
                @Override
                public HierarchicalStreamWriter createWriter(Writer out) {
                    return new PrettyPrintWriter(out) {
                        protected void writeText(QuickWriter writer, String text) {
                            if (text.startsWith(PREFIX_CDATA) && text.endsWith(SUFFIX_CDATA)) {
                                writer.write(text);
                            } else {
                                super.writeText(writer, text);
                            }
                        }
                    };
                }
            });
        } else {
            xstream = new XStream();
        }
        return xstream;
    }
}

4供炎、具體解析

//去掉亂七八糟數(shù)據(jù)
updateData = updateData.replace("</table>-200","</table>");
//XStream解析器：xml->bean
boolean flag = updateData.contains(XStreamUtil.PREFIX_CDATA);
XStream xStream = XStreamUtil.initXStream(flag);
xStream.processAnnotations(ZydUpdateDataBean.class);
ZydUpdateDataBean dataBean = (ZydUpdateDataBean) xStream.fromXML(updateData);
