jeesite快速開發平臺(七)----代碼生成原理
1、原理講解javascript
jeesite代碼生成用的是FreeMarker模板引擎結合xml技術來實現的，定義的模板都放在resources/templates/modules/gen下php
一看就知道crud就是基本的增刪改查，dao是數據庫操做，treetable是有關樹方面的模板，其中主要的配置文件就是config.xml,該文件中定義了生成的模板，以及java類型,查詢類型,字段顯示類型等一些數據。css

定義了子表，初看jeesite的代碼生成，有個困惑的地方就是,通常經過FreeMarker進行代碼生成定義的模板都是ftl格式的，而這裏倒是xml，什麼鬼，難道這裏不是用FreeMarker進行生成的??咱們先來看下xml文件中的內容就清楚了:html

其中的xml格式爲:
-
<?xml version="1.0" encoding="utf-8"?>
-
<template>
-
<name>controller
</name>
-
<filePath>src/main/java/${packageName}/${moduleName}/web/${subModuleName}

-
<fileName>${ClassName}Controller.java
</fileName>
-
<content><![CDATA[]]>
-
</content>
-
</template>
發現其中的奧祕沒，他把模板內容都放在了content標籤的CDATA[]區。並且config.xml有相對應的bean，用來實現xml轉對象:java

其中的代碼模板分類git
經過@XmlElement(name = "category")引用了GenCategory類，其中定義了主子模板
github
-
/**

-

-
* @version 2013-10-15
-
*/
-
@XmlRootElement(name="category")
-
public class GenCategory extends Dict {
-
-
private static final long serialVersionUID = 1L;
-
private List
<String> template; // 主表模板
-
private List
<String> childTableTemplate;// 子表模板
-
-
public static String CATEGORY_REF = "category-ref:";
-
-
public GenCategory() {
-
super();
-
}
-
-
@XmlElement(name = "template")
-
public List
<String> getTemplate() {
-
return template;
-
}
-
-
public void setTemplate(List
<String> template) {
-
this.template = template;
-
}
-
-
@XmlElementWrapper(name = "childTable")
-
@XmlElement(name = "template")
-
public List
<String> getChildTableTemplate() {

-
}
-
-
public void setChildTableTemplate(List
<String> childTableTemplate) {
-
this.childTableTemplate = childTableTemplate;
-
}
-
-
}
這兩個主子其實對應的就是
而其中的數據就是在配置業務表是初始化的一些數據,好比當咱們選擇某一張表時，而後點擊下一步web
就會調用GenTableController中的form方法，把一些配置參數設置進去spring
而後在genTableForm.jsp頁面進行渲染數據庫

注意其中的name屬性
name="columnList[${vs.index}].xxx"
因此在spring mvc數據綁定的時候能夠經過下標的形式來傳值
業務表配置好以後，就是生成代碼，新建生成方案配置，而後輸入一些必須的信息
點擊保存並生成代碼，會調用GenSchemeController中的save()方法，傳入一些參數
而後調用genSchemeService.save()方法進行生成
若是是1的話就生成代碼
generateCode方法以下:
-
private String generateCode(GenScheme genScheme){
-
-
StringBuilder result = new StringBuilder();
-
-
// 查詢主表及字段列
-
GenTable genTable = genTableDao.get(genScheme.getGenTable().getId());
-
genTable.setColumnList(genTableColumnDao.findList(new GenTableColumn(new GenTable(genTable.getId()))));
-
-
// 獲取全部代碼模板
-
GenConfig config = GenUtils.getConfig();
-
-
// 獲取模板列表
-
List
<GenTemplate> templateList = GenUtils.getTemplateList(config, genScheme.getCategory(), false); //獲取全部不包含childTableTemplateList的數據
-
List
<GenTemplate> childTableTemplateList = GenUtils.getTemplateList(config, genScheme.getCategory(), true);
-
-
// 若是有子表模板，則須要獲取子表列表
-
if (childTableTemplateList.size() > 0){
-
GenTable parentTable = new GenTable();
-
parentTable.setParentTable(genTable.getName());
-
genTable.setChildList(genTableDao.findList(parentTable));
-
}
-
-
// 生成子表模板代碼
-
for (GenTable childTable : genTable.getChildList()){
-
childTable.setParent(genTable);
-
childTable.setColumnList(genTableColumnDao.findList(new GenTableColumn(new GenTable(childTable.getId()))));
-
genScheme.setGenTable(childTable);
-
Map
<String, Object> childTableModel = GenUtils.getDataModel(genScheme);
-
for (GenTemplate tpl : childTableTemplateList){
-
result.append(GenUtils.generateToFile(tpl, childTableModel, genScheme.getReplaceFile()));
-
}
-
}
-
-
// 生成主表模板代碼
-
genScheme.setGenTable(genTable);
-
Map
<String, Object> model = GenUtils.getDataModel(genScheme);
-
for (GenTemplate tpl : templateList){
-
result.append(GenUtils.generateToFile(tpl, model, genScheme.getReplaceFile()));
-
}
-
return result.toString();
-
}
該方法主要是作一些，獲取模板，而後進行數據綁定等一些工做。其中的
-
// 獲取模板列表
-
List
<GenTemplate> templateList = GenUtils.getTemplateList(config, genScheme.getCategory(), false); //獲取全部不包含childTableTemplateList的數據
-
List
<GenTemplate> childTableTemplateList = GenUtils.getTemplateList(config, genScheme.getCategory(), true);
getTemplateList方法爲
-
/**
-
* 根據分類獲取模板列表
-
* @param config
-
* @param category
-
* @param isChildTable 是不是子表
-
* @return
-
*/
-
public static List
<GenTemplate> getTemplateList(GenConfig config, String category, boolean isChildTable){
-
List
<GenTemplate> templateList = Lists.newArrayList();
-
if (config !=null && config.getCategoryList() != null && category != null){
-
for (GenCategory e : config.getCategoryList()){
-
if (category.equals(e.getValue())){
-
List
<String> list = null;
-
if (!isChildTable){
-
list = e.getTemplate();
-
}else{
-
list = e.getChildTableTemplate();
-
}
-
if (list != null){
-
for (String s : list){
-
if (StringUtils.startsWith(s, GenCategory.CATEGORY_REF)){
-
templateList.addAll(getTemplateList(config, StringUtils.replace(s, GenCategory.CATEGORY_REF, ""), false));
-
}else{
-
GenTemplate template = fileToObject(s, GenTemplate.class);
-
if (template != null){
-
templateList.add(template);
-
}
-
}
-
}
-
}
-
break;
-
}
-
}
-
}
-
return templateList;
-
}
經過標誌位來獲取
主表，子表模板， 生成文件的方法是GenUtils.generateToFile(tpl, model, genScheme.getReplaceFile())
-
/**
-
* 生成到文件
-
* @param tpl
-
* @param model
-
* @param isReplaceFile
-
* @return
-
*/
-
public static String generateToFile(GenTemplate tpl, Map
<String, Object> model, boolean isReplaceFile){
-
// 獲取生成文件
-
String fileName = Global.getProjectPath() + File.separator
-
+ StringUtils.replaceEach(FreeMarkers.renderString(tpl.getFilePath() + "/", model),
-
new String[]{"//", "/", "."}, new String[]{File.separator, File.separator, File.separator})
-
+ FreeMarkers.renderString(tpl.getFileName(), model);
-
logger.debug(" fileName === " + fileName);
-
-
// 獲取生成文件內容
-
String content = FreeMarkers.renderString(StringUtils.trimToEmpty(tpl.getContent()), model);
-
logger.debug(" content === \r\n" + content);
-
-
// 若是選擇替換文件，則刪除原文件
-
if (isReplaceFile){
-
FileUtils.deleteFile(fileName);
-
}
-
-
// 建立並寫入文件
-
if (FileUtils.createFile(fileName)){
-
FileUtils.writeToFile(fileName, content, true);
-
logger.debug(" file create === " + fileName);
-
return "生成成功："+fileName+"
<br/>";
-
}else{
-
logger.debug(" file extents === " + fileName);
-
return "文件已存在："+fileName+"
<br/>";
-
}
-
}
生成成功以後，會有以下提示:
