Webservice 接口调用

• 最近项目中频繁遇到web service接口调用，调用起来麻烦，若使用wsimport生成客户端的方式调用，造成项目代码臃肿，简单整理个ws调用工具，便于在项目开发中使用。

• Request 请求报文

public class Request {

    private String url;

    private String body;
    /**账号信息*/
    private Account account;


    public String getUrl() {

    }


    public Account getAccount() {
        return account;
    }


    public void setAccount(Account account) {
        this.account = account;
    }

    @Override
    public String toString() {
        return "Request [url=" + url + ", body=" + body + ", account=" + account + "]";
    }

    /**
     * 账号信息

     */
    public class Account{
        /**账号*/
        private String username;
        /**密码*/
        private String password;
        public String getUsername() {
            return username;
        }
        public void setUsername(String username) {
            this.username = username;
        }
        public String getPassword() {
            return password;
        }
        public void setPassword(String password) {
            this.password = password;
        }

        @Override
        public String toString() {
            return "Account [username=" + username + ", password=" + password + "]";
