基于springboot+bootstrap+mysql+redis搭建一套完整的权限架构【五】【编写基础代码快速生成工具】
通过第四章我们编写了基础开发工具，但是大家会发现我们每开发一个新的模块都要重写一次从dao到xml层的代码，很明显很多都是重复的开发工作，那我们是否可以直接编写一个工具快速生成我们的代码呢？很明显这完全是没有问题的本章我们将实现使用快速生成工具一秒生成我们的所有的代码，该工具是基于从数据库读取表来实现动态生成我们的代码。
首先我们在我们的com.csdn包底下我们新建一个codeUtil包如下所示：
首先我们新建一个我们的列的模型（ColumnModel.java）如下：
/**
* 列模型
*/
public class ColumnModel {
private boolean isPrimaryKey;
private boolean isAutoIncrement;
private String columnName;
private String dataType;
private String typeName;
private String columnClassName;
private String fieldName;
private String fieldType;
private int columnSize;
private String columnDef;
private String remarks;
public boolean isPrimaryKey() {
return isPrimaryKey;
}
public void setPrimaryKey(boolean isPrimaryKey) {
this.isPrimaryKey = isPrimaryKey;
}
public boolean isAutoIncrement() {
return isAutoIncrement;
}
public void setAutoIncrement(boolean isAutoIncrement) {
this.isAutoIncrement = isAutoIncrement;
}
public String getColumnName() {
return columnName;
}
public void setColumnName(String columnName) {
this.columnName = columnName;
}
public String getDataType() {
return dataType;
}
public void setDataType(String dataType) {
this.dataType = dataType;
}
public String getTypeName() {
return typeName;
}
public void setTypeName(String typeName) {
this.typeName = typeName;
}
public int getColumnSize() {
return columnSize;
}
public void setColumnSize(int columnSize) {
this.columnSize = columnSize;
}
public String getRemarks() {
return remarks;
}
public void setRemarks(String remarks) {
this.remarks = remarks;
}
@Override
public String toString() {
return "ColumnModel [columnName=" + columnName + ", dataType="
+ dataType + ", typeName=" + typeName + ", columnClassName="
+ columnClassName + ", fieldName=" + fieldName + ", fieldType="
+ fieldType + ", columnSize=" + columnSize + ", columnDef="
+ columnDef + ", remarks=" + remarks + "]";
}
public String getColumnDef() {
return columnDef;
}
public void setColumnDef(String columnDef) {
this.columnDef = columnDef;
}
public String getColumnClassName() {
return columnClassName;
}
public void setColumnClassName(String columnClassName) {
this.columnClassName = columnClassName;
}
public String getFieldName() {
return fieldName;
}
public void setFieldName(String fieldName) {
this.fieldName = fieldName;
}
public String getFieldType() {
return fieldType;
}
public void setFieldType(String fieldType) {
this.fieldType = fieldType;
}
}接着我们创建我们的表结构的模型（TableModel.java）如下：
/**
* 表结构封装
* */
public class TableModel {
//表名
private String tableName;
//主键列
private List primaryKeyColumns;
//列
private List columns;
//需要引入包
private Set imports;
public String getTableName() {
return tableName;
}
public void setTableName(String tableName) {
this.tableName = tableName;
}
public List getPrimaryKeyColumns() {
return primaryKeyColumns;
}
public void setPrimaryKeyColumns(List primaryKeyColumns) {
this.primaryKeyColumns = primaryKeyColumns;
}
public List getColumns() {
return columns;
}
public void setColumns(List columns) {
this.columns = columns;
}
public Set getImports() {
return imports;
}
public void setImports(Set imports) {
this.imports = imports;
}
} public class JdbcUtil {
private static String properties_file_uri = null;
public static Properties configs;
public static void setPropertiesURL(String uri){

}
} 到此我们已经开发完成了我们的代码快速生成工具类，接着大家在GenCodeUtil.java中我们直接执行我们的genFiles("作者","数据库表名","基础工具包路径【com.csdn.demo.common.base】"，”java代码生成的路径“,"mybatis代码生成的路径","实体名","查询实体名","读取的配置文件的名字");我们此处则开始试着快速生成一份我们的代码，首先我们在PDM中设计一张字典表如下所示：
接着我们在数据执行生成我们的dict表的数据库字典脚本，然后我们在GenCodeUtil的main方法中执行我们的快速生成代码如下：
执行好该代码我们会发现我们的工程中已经多出来了以下的代码：
通过上图我们可以很明显的看到我们的代码已经生成成功了，那么接下来我们重新加载下我们的项目我们访问下我们的swagger2接口我们会发现我们的生成的代码已经生效了：
到此处我们很明显的发现我们生成的代码已经生效了，那么以后我们每当有一个新的模块的开发那么我们只要设计好数据库，后续我们就可以快速的生成代码，大大简化我们的开发工作，下一章将讲解如何集成bootsrap。
