log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
至此，maven整合ssm框架的配置文件基本完成。如果项目结构一致，基本把各配置文件的ssm替换成项目名就可以了。

3 以下为测试内容
3.1 用MP的Generator生成代码
首先看下我数据库创建的测试表，代码生成器类
MpGenerator.java文件
package com.ssm.utils;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.GlobalConfig;
import com.baomidou.mybatisplus.generator.config.PackageConfig;
import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.converts.MySqlTypeConvert;
import com.baomidou.mybatisplus.generator.config.rules.DbColumnType;
import com.baomidou.mybatisplus.generator.config.rules.DbType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
public class MpGenerator {
/**
* <p>
* MySQL 生成演示
* </p>
*/
public static void main(String[] args) {
AutoGenerator mpg = new AutoGenerator();
// 全局配置
GlobalConfig gc = new GlobalConfig();
gc.setOutputDir("D://");
gc.setFileOverride(true);
gc.setActiveRecord(true);
gc.setEnableCache(false); // XML 二级缓存
gc.setBaseResultMap(true); // XML ResultMap
gc.setBaseColumnList(true); // XML columList
gc.setAuthor("ellen");
// 自定义文件命名，注意 %s 会自动填充表实体属性！
// gc.setMapperName("%sDao");
// gc.setXmlName("%sDao");
// gc.setServiceName("MP%sService");
// gc.setServiceImplName("%sServiceDiy");
// gc.setControllerName("%sAction");
mpg.setGlobalConfig(gc);
// 数据源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setDbType(DbType.MYSQL);
dsc.setTypeConvert(new MySqlTypeConvert(){
// 自定义数据库表字段类型转换【可选】
@Override
public DbColumnType processTypeConvert(String fieldType) {
System.out.println("转换类型：" + fieldType);
// 注意！！processTypeConvert 存在默认类型转换，如果不是你要的效果请自定义返回、非如下直接返回。
return super.processTypeConvert(fieldType);
}
});
dsc.setDriverName("com.mysql.jdbc.Driver");
dsc.setUsername("root");
dsc.setPassword("123456");
dsc.setUrl("jdbc:mysql://localhost:3306/ssm?characterEncoding=utf8");
mpg.setDataSource(dsc);
// 策略配置
StrategyConfig strategy = new StrategyConfig();
// strategy.setCapitalMode(true);// 全局大写命名 ORACLE 注意
// strategy.setTablePrefix(new String[] { "tlog_", "tsys_" });// 此处可以修改为您的表前缀
strategy.setNaming(NamingStrategy.underline_to_camel);// 表名生成策略
strategy.setInclude(new String[] { "t_class"}); // 需要生成的表
// strategy.setExclude(new String[]{"test"}); // 排除生成的表
// 自定义实体父类
//strategy.setSuperEntityClass("com.kuyunEduShop.domain");
// 自定义实体，公共字段
// strategy.setSuperEntityColumns(new String[] { "test_id", "age" });
// 自定义 mapper 父类
// strategy.setSuperMapperClass("com.baomidou.demo.TestMapper");
// 自定义 service 父类
// strategy.setSuperServiceClass("com.baomidou.demo.TestService");
// 自定义 service 实现类父类
// strategy.setSuperServiceImplClass("com.baomidou.demo.TestServiceImpl");
// 自定义 controller 父类
// strategy.setSuperControllerClass("com.baomidou.demo.TestController");
// 【实体】是否生成字段常量（默认 false）
// public static final String ID = "test_id";
// strategy.setEntityColumnConstant(true);
// 【实体】是否为构建者模型（默认 false）
// public User setName(String name) {this.name = name; return this;}
// strategy.setEntityBuilderModel(true);
mpg.setStrategy(strategy);
// 包配置
PackageConfig pc = new PackageConfig();
pc.setParent("com");
pc.setModuleName("ssm");
mpg.setPackageInfo(pc);
// 注入自定义配置，可以在 VM 中使用 cfg.abc 【可无】
/* InjectionConfig cfg = new InjectionConfig() {
@Override
public void initMap() {
Map<String, Object> map = new HashMap<String, Object>();
map.put("abc", this.getConfig().getGlobalConfig().getAuthor() + "-mp");
this.setMap(map);
}
};
/*
// 自定义 xxList.jsp 生成
List<FileOutConfig> focList = new ArrayList<FileOutConfig>();
focList.add(new FileOutConfig("/template/list.jsp.vm") {
@Override
public String outputFile(TableInfo tableInfo) {
// 自定义输入文件名称
return "D://my_" + tableInfo.getEntityName() + ".jsp";
}
});
cfg.setFileOutConfigList(focList);
mpg.setCfg(cfg);
// 调整 xml 生成目录演示
focList.add(new FileOutConfig("/templates/mapper.xml.vm") {
@Override
public String outputFile(TableInfo tableInfo) {
return "/develop/code/xml/" + tableInfo.getEntityName() + ".xml";
}
});
cfg.setFileOutConfigList(focList);
mpg.setCfg(cfg);
*/
// 关闭默认 xml 生成，调整生成 至 根目录
/* TemplateConfig tc = new TemplateConfig();
tc.setXml(null);
mpg.setTemplate(tc);*/
// 自定义模板配置，可以 copy 源码 mybatis-plus/src/main/resources/templates 下面内容修改，
// 放置自己项目的 src/main/resources/templates 目录下, 默认名称一下可以不配置，也可以自定义模板名称
// TemplateConfig tc = new TemplateConfig();
// tc.setController("...");
// tc.setEntity("...");
// tc.setMapper("...");
// tc.setXml("...");
// tc.setService("...");
// tc.setServiceImpl("...");
// 如上任何一个模块如果设置 空 OR Null 将不生成该模块。
// mpg.setTemplate(tc);
// 执行生成
mpg.execute();
// 打印注入设置【可无】
// System.err.println(mpg.getCfg().getMap().get("abc"));
}
}
注意：
3.2 写一个Controller测试代码
HelloController.java文件
@Controller
public class HelloController {
/**
* 返回jsp视图
* @return
*/
@RequestMapping("/hello")
public String hello(){
Logger logger = Logger.getLogger(HelloController.class);
logger.info("log4j测试");
return "hello";
}
/**
* 返回json数据
* @return
*/
@RequestMapping("/student")
@ResponseBody
public TStudent student(){
TStudent student = new TStudent();
student.setId((long) 1);
student.setStudentName("张三");
student.setClassId((long) 2);
return student;
}
}注意：在WEB-INF下创建一个jsp文件夹，里面创建一个hello.jsp
3.3 运行结果
启动项目没有报错后，分别访问hello.action(返回jsp视图)和student.action(返回json格式数据)
4 完整项目代码
4.1 码云项目链接：https://gitee.com/ljf16/ssm/tree/master
注意：项目使用的开发环境是IDEA，项目拉下来可以直接跑(注意数据库连接信息)
