yaml文件的读取以及其工具类

由于在工作中会出现一系列以键值对形式选项参数对应，可以通过yaml文件进行读取文件流。

#计划审核表-查询类型
TCX_JHSBB_AUDIT_searchSblx:
  - valueData: 1
    displayName: 待审核
  - valueData: 2
    displayName: 已审核

YamlUtil

package ;

import ;
import ;
import ;
import ;

import ;
import ;

/**
 *  配置文件对应下拉集合显示
 * @author Lenovo
 */
public class YamlUtil {
	
	
	// 计划审核表-查询类型（计划审核、配合审核）
	public static final String TCX_JHSBB_AUDIT_SEARCHSBLX = "TCX_JHSBB_AUDIT_searchSblx"; // 查询类型
	
	
	/**
	 * 读取下拉状态配置参数List
	 * @param typeName
	 * @return
	 * @throws IOException
	 * @throws IllegalAccessException 
	 * @throws IllegalArgumentException 
	 */
	public static List<SelectModel> getTypePropertie(String typeName) throws IOException{
		String yamlPath = () + "conf/"; // yaml路径
		File yamlFile = new File(yamlPath);
		Yaml yaml = new Yaml();
		HashMap map = (new FileInputStream(yamlFile), );
		
		List<SelectModel> list = new ArrayList<SelectModel>();
		List contentList = (List)(typeName);
		for (Object item : contentList){
			(new SelectModel(((HashMap)item).get("valueData").toString(), ((HashMap)item).get("displayName").toString()));
		}
		return list;
	}
	
	/**
	 * 读取下拉状态配置参数返回map
	 * @param typeName
	 * @return
	 * @throws IOException
	 */
	public static Map<String,Object> getTypePropertieMap(String typeName) throws IOException{
		String yamlPath = () + "conf/"; // yaml路径
		File yamlFile = new File(yamlPath);
		Yaml yaml = new Yaml();
		HashMap hashMap = (new FileInputStream(yamlFile), );
		
		Map<String,Object> map = new HashMap<String,Object>();
		List contentList = (List)(typeName);
		for (Object item : contentList){
			(((HashMap)item).get("valueData").toString(), ((HashMap)item).get("displayName").toString());
		}
		return map;
	}
}

注意：这里需要导入一个包，可以在Maven中引入

	<dependency>
		    <groupId></groupId>
		    <artifactId>snakeyaml</artifactId>
		    <version>1.17</version>
		</dependency>

上面中还引入了一个PathUtil的路径工具类

package ;

import ;

import ;

import ;
import ;

/**
 * 路径工具类
 * 
 * @author
 * 
 */
public class PathUtil {

	/**
	 * 图片访问路径
	 * 
	 * @param pathType
	 *            图片类型 visit-访问；save-保存
	 * @param pathCategory
	 *            图片类别，如：话题图片-topic、话题回复图片-reply、商家图片
	 * @return
	 */
	public static String getPicturePath(String pathType, String pathCategory) {
		String strResult = "";
		HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder
				.getRequestAttributes()).getRequest();
		StringBuffer strBuf = new StringBuffer();
		if ("visit".equals(pathType)) {
		} else if ("save".equals(pathType)) {
			String projectPath = ().replaceAll("\\\\",
					"/");
			projectPath = splitString(projectPath, "bin/");

			(projectPath);
			("webapps/ROOT/");
		}

		strResult = ();

		return strResult;
	}

	private static String splitString(String str, String param) {
		String result = str;

		if ((param)) {
			int start = (param);
			result = (0, start);
		}

		return result;
	}
	
	/*
	 * 获取classpath1
	 */
	public static String getClasspath(){
		String path = ((().getContextClassLoader().getResource(""))+"../../").replaceAll("file:/", "").replaceAll("%20", " ").trim();	
		if((":") != 1){
			path =  + path;
		}
		return path;
	}
	
	/*
	 * 获取classpath2
	 */
	public static String getClassResources(){
		String path =  ((().getContextClassLoader().getResource(""))).replaceAll("file:/", "").replaceAll("%20", " ").trim();	
		if((":") != 1){
			path =  + path;
		}
		return path;
	}
	
	public static String PathAddress() {
		String strResult = "";

		HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder
				.getRequestAttributes()).getRequest();

		StringBuffer strBuf = new StringBuffer();

		(() + "://");
		(() + ":");
		(() + "");

		(() + "/");

		strResult = ();// +"ss/";//加入项目的名称

		return strResult;
	}
	
	
}

SelectModel

package ;


/**
 * 下拉绑定对象
 * @author zhanghd 2017-07-27
 *
 */
public class SelectModel {
	public SelectModel() {
		super();
	}
	
	public SelectModel(String valueData, String displayName) {
		super();
		 = valueData;
		 = displayName;
	}

	/**
	 * 下拉值
	 */
	private String valueData;
	/**
	 * 下拉显示内容
	 */
	private String displayName;

	public String getValueData() {
		return valueData;
	}

	public void setValueData(String valueData) {
		 = valueData;
	}

	public String getDisplayName() {
		return displayName;
	}

	public void setDisplayName(String displayName) {
		 = displayName;
	}
}

注意：在测试过程中，报了一个Caused by: : : Input length = 1

原因，中的指定配置文件编码不是UTF-8的，转换成UTF-8就行了。
