编写代码生成器
public static void main(String[] args) {
String url = "jdbc:mysql:///xdb";
String username = "root";
String password = "123456";
String author = "laocai";
String outputDir = "D:\\tmp\\spring\\x-admin\\src\\main\\java";
String basePackage = "com.lantu";
String moduleName = "sys";
String mapperLocation = "D:\\tmp\\spring\\x-admin\\src\\main\\resources\\mapper\\" + moduleName;
String tableName = "x_user,x_menu,x_role,x_role_menu,x_user_role";
String tablePrefix = "x_";
FastAutoGenerator.create(url, username, password)
.globalConfig(builder -> {
builder.author(author) // 设置作者
.enableSwagger() // 开启 swagger 模式
//.fileOverride() // 覆盖已生成文件
.outputDir(outputDir); // 指定输出目录
})
.packageConfig(builder -> {
builder.parent(basePackage) // 设置父包名
.moduleName(moduleName) // 设置父包模块名
.pathInfo(Collections.singletonMap(OutputFile.xml, mapperLocation)); // 设置mapperXml生成路径
})
.strategyConfig(builder -> {
builder.addInclude(tableName) // 设置需要生成的表名
.addTablePrefix(tablePrefix); // 设置过滤表前缀
})
.templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板,默认的是Velocity引擎模板
.execute();
}
启动类加注解
@MapperScan("com.lantu.*.mapper")

分页拦截器

public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
return interceptor;
}
}
密码加密处理,用BCryptPasswordEncoder,涉及登录逻辑改动
此处不提供密码更新,大家自行扩展,可以去实现前端右上角菜单的个人信息功能
利用MyBatisPlus做逻辑删除处理
mybatis-plus:
global-config:
db-config:
logic-delete-field: delete
logic-delete-value: 1
logic-not-delete-value: 0
