java基于xml配置的通用excel单表数据导入组件(二、xml配置文件解析加载)

1、BN_ImportExcel.java 对应xml主节点属性

package XXXXX.manage.importexcel;

import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;

public class BN_ImportExcel implements Serializable {

	/**
	 *
	 */
	private static final long serialVersionUID = -3837515724164300087L;

	private String name;
	private String initSQL;
	private String beforeSaveSQL;
	private String afterSaveSQL;
	private Map<String, BN_Column> excelColumn;
	private Map<String, BN_Column> systemColumn;

    public void addExcelColumn(String key, BN_Column column) {
        if (excelColumn == null) {
        	excelColumn = new HashMap<String, BN_Column>();
        }
        excelColumn.put(key, column);
    }  

    public void addSystemColumn(String key, BN_Column column) {
        if (systemColumn == null) {
        	systemColumn = new HashMap<String, BN_Column>();
        }
        systemColumn.put(key, column);
    }  

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

	public String getInitSQL() {
		return initSQL;
	}

	public void setInitSQL(String initSQL) {
		this.initSQL = initSQL;
	}

	public String getBeforeSaveSQL() {
		return beforeSaveSQL;
	}

	public void setBeforeSaveSQL(String beforeSaveSQL) {
		this.beforeSaveSQL = beforeSaveSQL;
	}

	public String getAfterSaveSQL() {
		return afterSaveSQL;
	}

	public void setAfterSaveSQL(String afterSaveSQL) {
		this.afterSaveSQL = afterSaveSQL;
	}

	public Map<String, BN_Column> getExcelColumn() {
		return excelColumn;
	}
	public void setExcelColumn(Map<String, BN_Column> excelColumn) {
		this.excelColumn = excelColumn;
	}
	public Map<String, BN_Column> getSystemColumn() {
		return systemColumn;
	}
	public void setSystemColumn(Map<String, BN_Column> systemColumn) {
		this.systemColumn = systemColumn;
	}

	public String toString() {
		StringBuffer sb = new StringBuffer();
		sb.append("{")
		.append("name:'").append(name).append("',")
		.append("initSQL:'").append(initSQL).append("',")
		.append("beforeSaveSQL:'").append(beforeSaveSQL).append("',")
		.append("afterSaveSQL:'").append(afterSaveSQL).append("',")
		.append("excelColumn:").append(excelColumn).append(",")
		.append("systemColumn:").append(systemColumn).append("'}");
		return sb.toString();
    }

}

　　2.BN_Column.java 对应详细字段属性配置

package XXXXXXXX.manage.importexcel;

import java.io.Serializable;

public class BN_Column implements Serializable {

	/**
	 *
	 */
	private static final long serialVersionUID = 3549142775670034730L;

	private String column;
	private String dataType;
	private int length;
	private boolean required;
	private boolean transfer;
	private String className;
	private String method;
	private String param;

	public String getColumn() {
		return column;
	}
	public void setColumn(String column) {
		this.column = column;
	}
	public String getDataType() {
		return dataType;
	}
	public void setDataType(String dataType) {
		this.dataType = dataType;
	}
	public int getLength() {
		return length;
	}
	public void setLength(int length) {
		this.length = length;
	}
	public boolean isRequired() {
		return required;
	}
	public void setRequired(boolean required) {
		this.required = required;
	}
	public boolean isTransfer() {
		return transfer;
	}
	public void setTransfer(boolean transfer) {
		this.transfer = transfer;
	}
	public String getClassName() {
		return className;
	}
	public void setClassName(String className) {
		this.className = className;
	}
	public String getMethod() {
		return method;
	}
	public void setMethod(String method) {
		this.method = method;
	}
	public String getParam() {
		return param;
	}
	public void setParam(String param) {
		this.param = param;
	}

	public String toString() {
		StringBuffer sb = new StringBuffer();
		sb.append("{")
		.append("column:'").append(column).append("',")
		.append("dataType:'").append(dataType).append("',")
		.append("length:").append(length).append(",")
		.append("required:").append(required).append(",")
		.append("transfer:").append(transfer).append(",")
		.append("className:'").append(className).append("',")
		.append("method:'").append(method).append("',")
		.append("param:'").append(param).append("'}");
		return sb.toString();
	}

}

　　3.解析xml为BN_ImportExcel对象

public class DAO_ImportExcel {
	private BN_ImportExcel xmlBean;
	private Map<String, BN_Column> excelColumn; // 列名称、字段定义映射
	private Map<String, BN_Column> systemColumn;// 系统内置字段定义

             private void loadXmlBean() {
		BeanReader beanReader = new BeanReader();
		// 配置BeanReader实例
		beanReader.getXMLIntrospector().getConfiguration()
				.setAttributesForPrimitives(false);
		beanReader.getBindingConfiguration().setMapIDs(false); // 不自动生成ID
		// 注册要转换对象的类，并指定根节点名称
		BufferedReader br = null;
		try {
			beanReader.registerBeanClass("importExcel", BN_ImportExcel.class);
			br = new BufferedReader(new InputStreamReader(
					new FileInputStream(new File(
							PathUtil.getPath("/WEB-INF/excel/" + tableImport + ".xml"))), "GBK"));
			// 将XML解析Java Object
			xmlBean = (BN_ImportExcel) beanReader.parse(br);
			excelColumn = xmlBean.getExcelColumn();
			systemColumn = xmlBean.getSystemColumn();
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IntrospectionException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (SAXException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {
			if (br != null){
				try {
					br.close();
				} catch (IOException e) {
				}
			}
		}
	}
}
