最近在研究spring boot、mybatis-plus、shiro等技术框架的整合，为此设计了一套简单的权限系统，在其中实现了主要的业务功能，增加一些功能代码和技术技巧，提高自己的代码能力

                </plugin>
            </plugins>
        </build>
    
    </project>

第一步，先把mybatis-plus的代码生成器整合进去

<dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-generator</artifactId>
                <version>${mybatis-plus-generator.version}</version>
            </dependency>
            <dependency>
                <groupId>org.freemarker</groupId>
                <artifactId>freemarker</artifactId>
                <version>${freemarker.version}</version>
            </dependency>```
    第二步，编写代码生成器的代码

public class CodeGenerate {
    public static void main(String[] args) {
    
        //用来获取Mybatis-Plus.properties文件的配置信息
        final ResourceBundle rb = ResourceBundle.getBundle("mybatis-plus");
    
        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();
    
        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        gc.setOutputDir(rb.getString("OutputDir"));
        gc.setOpen(false);
        gc.setBaseResultMap(true);
        gc.setBaseColumnList(true);
        gc.setAuthor(rb.getString("author"));
        gc.setMapperName("%sMapper");
        gc.setXmlName("%sMapper");
        gc.setServiceName("%sService");
        gc.setServiceImplName("%sServiceImpl");
        gc.setControllerName("%sController");
        mpg.setGlobalConfig(gc);
    
        // 数据源配置
        com.baomidou.mybatisplus.generator.config.DataSourceConfig dsc = new DataSourceConfig();
        dsc.setDbType(DbType.MYSQL);
        dsc.setUrl(rb.getString("url"));
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUsername(rb.getString("userName"));
        dsc.setPassword(rb.getString("password"));
        mpg.setDataSource(dsc);
    
    
        // 自定义配置
        InjectionConfig cfg = new InjectionConfig() {
            @Override
            public void initMap() {
                // to do nothing
            }
        };
        List<FileOutConfig> focList = new ArrayList<>();
        focList.add(new FileOutConfig("/templates/mapper.xml.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                // 自定义输入文件名称
                return rb.getString("OutputDirXml") + "/mapper/" + rb.getString("className") + "/" + tableInfo.getEntityName() + StringPool.DOT_XML;
            }
        });
        cfg.setFileOutConfigList(focList);
        mpg.setCfg(cfg);
        mpg.setTemplate(new TemplateConfig().setXml(null));
    
        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        strategy.setEntityLombokModel(true);
        strategy.setInclude(new String[]{rb.getString("tableName")});
        mpg.setStrategy(strategy);
        mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        mpg.execute();
    
    }

\}\`\`\`  
第三步：自动生成器的配置

#此处为本项目src所在路径（代码生成器输出路径）
    OutputDir=/Users/yiliu/IdeaProjects/agile-demo/src/main/java
    #mapper.xml的生成位置
    OutputDirXml=/Users/yiliu/IdeaProjects/agile-demo/src/main/java
    #数据库表名(此处切不可为空，如果为空，则默认读取数据库的所有表名)
    tableName=sys_log
    #装代码的文件夹名
    className=
    #设置作者
    author=liuyi
    #自定义包路径
    parent=
    #数据库地址
    url=jdbc:mysql://localhost:3306/agile_demo?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true&tinyInt1isBit=false
    userName=root
    password=
