1、创建zy.xml
<?xml version="1.0" encoding="UTF-8"?> <zy> <person> <name>sqx</name> <age>21</age> <img>C:/Users/qiuxiang/Desktop/codeStyle.jpg</img> </person> <person> <name>tyh</name> <age>23</age> <img>C:/Users/qiuxiang/Desktop/c1.jpeg</img> </person> <person> <name>zzj</name> <age>20</age> <img>C:/Users/qiuxiang/Desktop/c2.jpeg</img> </person> </zy>
第一题：遍历目录，将图片存入数据库（数据库中包含大对象字段）
（1）创建数据库
（2）DButil.java(数据库连接)导入mysql连接jar包
public class DButil {
private static String Driver = "com.mysql.jdbc.Driver";
private static String url = "jdbc:mysql://数据库地址?useUnicode=true&characterEncoding=UTF-8";
private static String userName = "用户名";
private static String passWord = "密码";
private static Connection conn = null;
public DButil(){
try {
Class.forName(Driver);
conn = DriverManager.getConnection(url, userName, passWord);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
public Connection getconn() {
return conn;
}
public void closeconn() throws SQLException{
conn.close();
}
}
（3）XML2DB.java
public class XML2DB {
/**
* 将目录中的图片存入数据库
*/
public void ins(InputStream sq,File f){
DButil db = new DButil();
Connection conn = db.getconn();
try {
String sql = "insert into imf(img) values(?)";
PreparedStatement st = conn.prepareStatement(sql);
st.setBinaryStream(1, sq,(int)f.length());
System.out.println(sq);
st.executeUpdate();
} catch (Exception e) {
e.printStackTrace();
}
}
public void readxml(){
try{
File f = new File("C:/Users/qiuxiang/Desktop/zy.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(f);
NodeList List = doc.getElementsByTagName("person");
for (int i = 0; i < List.getLength(); i++) {
String img = doc.getElementsByTagName("img").item(i).getFirstChild().getNodeValue();
File fi = new File(img);
FileInputStream fis = new FileInputStream(fi);
ins(fis,fi);
}
}catch(Exception e){
}
}
public static void main(String[] args) {
XML2DB rx = new XML2DB();
rx.readxml();
}
}
第二题：遍历目录，将文件信息形成XML文件（包含文件名、创建时间、文件位置、文件大小）
（1）Data2XML.java（为了方便，这里直接读取zy.xml中的图片信息）
public class Data2XML {
/**
* 读取文件信息并生成xml
*/
List<String> filelist;
public void readxml(){
filelist = new ArrayList<>();
try{
File f = new File("C:/Users/qiuxiang/Desktop/zy.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(f);
NodeList List = doc.getElementsByTagName("person");
for (int i = 0; i < List.getLength(); i++) {
String img = doc.getElementsByTagName("img").item(i).getFirstChild().getNodeValue();
filelist.add(img);
}
}catch(Exception e){
}
}
public void createXMLByDOM(File dest) {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
readxml();
try {
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.newDocument();
Element bookstore = document.createElement("fileinfo");
for (int i = 0; i < filelist.size(); i++) {
File f = new File(filelist.get(i));
Element file = document.createElement("file");
file.setAttribute("id", "1");
Element fname = document.createElement("name");
fname.setTextContent(f.getName());
file.appendChild(fname);
Element createtime = document.createElement("createtime");
createtime.setTextContent(new Date(f.lastModified()).toString());
file.appendChild(createtime);
Element path = document.createElement("path");
path.setTextContent(f.getPath());
file.appendChild(path);
Element size = document.createElement("size");
size.setTextContent(f.length()/1024+"kb");
file.appendChild(size);
bookstore.appendChild(file);
}
document.appendChild(bookstore);
TransformerFactory tff = TransformerFactory.newInstance();
Transformer tf = tff.newTransformer();
tf.setOutputProperty(OutputKeys.INDENT, "yes");
tf.transform(new DOMSource(document), new StreamResult(dest));
} catch (ParserConfigurationException e) {
e.printStackTrace();
} catch (TransformerConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TransformerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[] args) {
Data2XML dx = new Data2XML();
File f = new File("C:/Users/qiuxiang/Desktop/fi.xml");
dx.createXMLByDOM(f);
}
}
第三题：构建Webservices，并获取某XML文件中某元素内容（参数为文件名、字段名，返回元素内容）
（1）GetMsgService.java
@WebService
public class GetMsgService {
/**
*
*/
static List<String> list;
@WebMethod(operationName="getinfo")
public @WebResult(name="info")List<String> getinfo(@WebParam(name="filepath")String filepath,@WebParam(name="itemname")String itemname){
list = new ArrayList<>();
try{
File f = new File(filepath);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(f);
NodeList List = doc.getElementsByTagName(itemname);
for (int i = 0; i < List.getLength(); i++) {
slist(List.item(i));
}
for (int i = 0; i < list.size(); i++) {
System.out.println(list.get(i));
}
}catch(Exception e){
}
return list;
}
public static void slist(Node node){
if(node.getNodeType()==node.TEXT_NODE){
node.getTextContent().replaceAll(" ", "");
if (!node.getTextContent().trim().equals("")) {
list.add(node.getTextContent());
}
}
NodeList lists=node.getChildNodes();
for(int i=0;i<lists.getLength();i++){
Node child=lists.item(i);
slist(child);
}
}
public static void main(String[] args) {
Endpoint.publish("http://localhost:8888/sqx/GetMsgService", new GetMsgService());
System.out.println("start success");
}
}
测试
1、在命令行中输入
wsimport -s D:\web\lanqiao\lanqiao\Webclient\\src -p com.itim.webservice -keep http://localhost:8888/sqx/GetMsgService?wsdl
其中D:\web\lanqiao\lanqiao\Webclient\\src 为输出路径 com.itim.webservice为包名
刷新后可见
创建test.java
public class test {
/**
*
*/
public static void main(String[] args) {
GetMsgServiceService gmss = new GetMsgServiceService();
GetMsgService gi = gmss.getGetMsgServicePort();
List<String> gif = gi.getinfo("C:/Users/qiuxiang/Desktop/zy.xml", "person");
for (int i = 0; i < gif.size(); i++) {
System.out.println(gif.get(i));
}
}
}
控制台输出结果
