4.2 编码
4.2.1 常量类

}
4.2.2 工具类
（1）DbUtil数据库工具类
package freemarker.util;import freemarker.param.ColumnClass;
import freemarker.param.TableClass;
import lombok.Getter;
import lombok.Setter;import java.sql.*;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;/*** 数据库工具类*/
@Setter
@Getter
public class DbUtil {//数据库连接地址private String url = "jdbc:mysql://localhost:3306/heima_leadnews_wemedia?useSSL=false&nullCatalogMeansCurrent=true&serverTimezone=UTC";//数据库用户名private String username = "root";//数据库密码private String password = "123456";//数据库驱动private String driver = "com.mysql.jdbc.Driver";//数据库名称private String dbName = null;private Connection connection =null;/*** 获取jdbc链接* @return* @throws Exception*/public Connection getConnection() throws Exception{Properties pro = new Properties();pro.setProperty("user", username);pro.setProperty("password", password);pro.put("useInformationSchema", "true");//获取mysql表注释//pro.setProperty("remarksReporting","true");//获取oracle表注释Class.forName(driver);connection = DriverManager.getConnection(url, pro);return connection;}/*** 获取当前数据库下的所有表名称及注释* @return* @throws Exception*/public List getAllTables() throws Exception {List list = new ArrayList<>();//获取链接Connection conn = getConnection();//获取元数据DatabaseMetaData metaData = conn.getMetaData();//获取所有的数据库表信息ResultSet rs = metaData.getTables(dbName!=null?dbName:conn.getCatalog(), "%", "%", new String[]{"TABLE"});while (rs.next()) {TableClass tableClass = new TableClass();tableClass.setTableName(rs.getString(3));tableClass.setTableComment(rs.getString(5));list.add(tableClass);}return list;}/*** 获取某张表的所有列* @param tableName* @return* @throws Exception*/public List getAllColumns(String tableName) throws Exception {List list = new ArrayList<>();//获取链接Connection conn = getConnection();//获取元数据DatabaseMetaData metaData = conn.getMetaData();//获取所有的数据库某张表所有列信息ResultSet rs = metaData.getColumns(dbName!=null?dbName:conn.getCatalog(), "%", tableName,"%");while(rs.next()) {ColumnClass columnClass = new ColumnClass();columnClass.setColumnName(rs.getString("COLUMN_NAME"));columnClass.setColumnType(rs.getString("TYPE_NAME"));columnClass.setColumnComment(rs.getString("REMARKS"));columnClass.setChangeColumnName(StrUtil.changeColumnStr(rs.getString("COLUMN_NAME")));list.add(columnClass);}return list;}/*** 关闭链接*/public void closeConnection(){try {connection.close();} catch (SQLException e) {e.printStackTrace();}};} （2）字符串处理工具类
package freemarker.util;/*** 字符串处理工具类*/
public class StrUtil {/*** 去掉下划线转驼峰 user_name -> userName* @param str* @return*/public static String changeColumnStr(String str) {String name = str;if (name.indexOf("_") > 0 && name.length() != name.indexOf("_") + 1) {int lengthPlace = name.indexOf("_");name = name.replaceFirst("_", "");String s = name.substring(lengthPlace, lengthPlace + 1);s = s.toUpperCase();str = name.substring(0, lengthPlace) + s + name.substring(lengthPlace + 1);} else {return str;}return changeColumnStr(str);}/*** 去掉下划线转驼峰 tb_user -> TbUser* @param str* @return*/public static String changeTableStr(String str) {String s = changeColumnStr(str);return s.substring(0,1).toUpperCase()+s.substring(1);}
}（3）FreeMarker模版工具类
package freemarker.util;import freemarker.cache.FileTemplateLoader;
import freemarker.cache.NullCacheStorage;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateExceptionHandler;import java.io.File;
import java.io.IOException;
import java.io.UnsupportedEncodingException;/*** FreeMarker模版工具类*/
public class FreeMarkerTemplateUtils {private FreeMarkerTemplateUtils(){}private static final Configuration CONFIGURATION = new Configuration(Configuration.VERSION_2_3_22);static{//ClassTemplateLoader方式：需要将模版放在FreeMarkerTemplateUtils类所在的包，加载模版时会从该包下加载//CONFIGURATION.setTemplateLoader(new ClassTemplateLoader(FreeMarkerTemplateUtils.class,""));try {String path = java.net.URLDecoder.decode(FreeMarkerTemplateUtils.class.getClassLoader().getResource("").getPath(),"utf-8");//FileTemplateLoader方式：需要将模版放置在classpath目录下 目录有中文也可以CONFIGURATION.setTemplateLoader(new FileTemplateLoader(new File(path)));} catch (UnsupportedEncodingException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}CONFIGURATION.setDefaultEncoding("UTF-8");CONFIGURATION.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER);CONFIGURATION.setCacheStorage(NullCacheStorage.INSTANCE);}public static Template getTemplate(String templateName) throws IOException {try {return CONFIGURATION.getTemplate(templateName);} catch (IOException e) {throw e;}}public static void clearCache() {CONFIGURATION.clearTemplateCache();}
}
4.2.3 实体类
（1）表实体类
package freemarker.param;import lombok.Data;@Data
public class TableClass {/*** 表名 tb_user**/private String tableName;/*** 表注释**/private String tableComment;}
（2）列实体类
package freemarker.param;import lombok.Data;@Data
public class ColumnClass {/*** 数据库字段名称 user_name**/private String columnName;/*** 数据库字段类型**/private String columnType;/*** 数据库字段首字母小写且去掉下划线字符串 userName**/private String changeColumnName;/*** 数据库字段注释**/private String columnComment;}
（3）模版相关参数类
package freemarker.param;import lombok.Data;
import org.apache.commons.lang3.StringUtils;import java.text.SimpleDateFormat;
import java.util.Date;@Data
public class TemplatePathParam {private String currentDate = new SimpleDateFormat("yyyy/MM/dd").format(new Date());//包名 com.itheima.userprivate String packageName;//代码生成路径 D:\\pathprivate String basePath;//项目名称 英文 比如itheima-userprivate String projectName;//作者private String author ;//实体类生成的绝对路径private String entityPath;//vo实体类生成的绝对路径private String entityVoPath;//Dto实体类生成的绝对路径private String entityDtoPath;//mapper生成绝对路径private String mapperPath;//mapper映射文件生成的绝对路径private String mapperXmlPath;//service接口生成的绝对路径private String servicePath;//service实现类生成的绝对路径private String serviceImplPath;//controller生成的绝对路径private String controllerPath;//pom文件生成的绝对路径private String pomPath;//application.yml文件生成的绝对路径private String applicationYmlPath;public TemplatePathParam(String packageName, String basePath, String projectName, String author) {if(StringUtils.isBlank(packageName)|| StringUtils.isBlank(basePath)|| StringUtils.isBlank(author)|| StringUtils.isBlank(projectName)){throw new RuntimeException("参数不能为空");}this.packageName = packageName;this.basePath = basePath;this.author = author;this.projectName = projectName;String[] split = packageName.split("\\.");// D:\\path\\itheima-user\\src\\main\\java\\com\\itheima\\userString javaModelPath = basePath+"\\"+projectName+"\\src\\main\\java\\"+split[0]+"\\"+split[1]+"\\"+split[2];String xmlModelPath = basePath+"\\"+projectName+"\\src\\main\\resources\\"+split[0]+"\\"+split[1]+"\\"+split[2];this.setEntityPath(javaModelPath+"\\entity");this.setMapperPath(javaModelPath+"\\mapper");this.setMapperXmlPath(xmlModelPath+"\\mapper");this.setServicePath(javaModelPath+"\\service");this.setServiceImplPath(javaModelPath+"\\service\\impl");this.setControllerPath(javaModelPath+"\\http\\controller");this.setEntityVoPath(javaModelPath+"\\http\\vo");this.setEntityDtoPath(javaModelPath+"\\http\\dto");this.setEntityDtoPath(javaModelPath+"\\http\\dto");this.setPomPath(basePath+"\\"+projectName);this.setApplicationYmlPath(basePath+"\\"+projectName+"\\src\\main\\resources");}}4.2.4 代码生成器入口类
