2 Config

2.1 全局配置ApplicationConfig

@ComponentScan(basePackages= "com.cc.ssmDemo")
@MapperScan(basePackages = "cm.cc.ssmDemo.mapper")
@EnableTransactionManagement
@Configuration
@Import({DBConnectConfig.class,MvcConfig.class})
public class ApplicationConfig extends WebMvcConfigurationSupport{

    @Autowired
    private ConfigurableConversionService conversionService;

   @Autowired
    private DateConvert dateConvert;

    public ApplicationConfig() {
        System.out.println("应用启动……");
    }

    //日期转化器
    @PostConstruct
    public void initEditableAvlidation(){
        if (conversionService!=null){
            conversionService.addConverter(dateConvert);
        }
    }

    // jsp视图解析器
    @Bean
    public InternalResourceViewResolver resourceViewResolver(){
        InternalResourceViewResolver ir = new InternalResourceViewResolver();
        ir.setPrefix("/WEB-INF/jsp/");
        ir.setSuffix(".jsp");
        return ir;
    }

   /* // 配置 multipart类型解析器
    @Bean
    public MultipartResolver multipartResolver(){
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        resolver.setDefaultEncoding("utf-8");
        resolver.setMaxUploadSize(50*1024*1024);
        resolver.setMaxInMemorySize(40*1024*1024);
        return resolver;
    }*/

}

2.2 mvc配置

不拦截静态资源，配置过滤器，json数据转换器，跨域等

@Configuration
@EnableWebMvc
public class MvcConfig implements WebMvcConfigurer {
    /*@Autowired
   private MyHandlerIntercepter intercepter1;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(intercepter1);
    }
*/
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer conf) {
        conf.enable();
    }

  /*  public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.jsp("/WEB-INF/jsp/", ".jsp");
        registry.enableContentNegotiation(new MappingJackson2JsonView());
    }*/

    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/js/**").addResourceLocations("/js/");
    }

    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        // 1、需要先定义一个·convert转换消息的对象；
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        // 2、添加fastjson的配置信息，比如 是否要格式化返回json数据
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        // 3、在convert中添加配置信息.
        fastConverter.setFastJsonConfig(fastJsonConfig);
        // 4、将convert添加到converters当中.
        converters.add(fastConverter);
    }


    @Override
    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
        configurer.favorPathExtension(true)
                .ignoreAcceptHeader(true)
                .parameterName("mediaType")
                .defaultContentType(MediaType.TEXT_HTML)
                .mediaType("html", MediaType.TEXT_HTML)
                .mediaType("json", MediaType.APPLICATION_JSON);
    }

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedOrigins("*")
        .allowedMethods("*").allowedHeaders("*")
        .allowCredentials(true);
    }
}

2.3 配置数据源

@Configuration
@EnableTransactionManagement
@PropertySource("classpath:db.properties")
public class DBConnectConfig {

    @Value("${db.driver}")
    private String DRIVER;

    @Value("${db.url}")
    private String URL;

    @Value("${db.username}")
    private String USERNAME;

    @Value("${db.password}")
    private String PASSWORD;

    @Bean
    public DataSourceTransactionManager dataSourceTransactionManager(DataSource dataSource){
        DataSourceTransactionManager dm = new DataSourceTransactionManager();
        dm.setDataSource(dataSource);
        return dm;
    }

    @Bean
    public SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource){
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(dataSource);
        return factoryBean;
    }

    /*@Bean
    public PlatformTransactionManager transactionManager(DataSource dataSource) {
        DataSourceTransactionManager dataSourceTransactionManager = new DataSourceTransactionManager(dataSource);
        return dataSourceTransactionManager;

    }*/

    @Bean
    public DataSource dataSource(){
        PooledDataSource dataSource = new PooledDataSource();
        dataSource.setDriver(DRIVER);
        dataSource.setUrl(URL);
        dataSource.setUsername(USERNAME);
        dataSource.setPassword(PASSWORD);
        return dataSource;
    }
}

3 代码生成器

public class CodeGenerator {



    public static void main(String[] args) {
        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        gc.setFileOverride(true);
        gc.setActiveRecord(true);// 开启 activeRecord 模式
        gc.setEnableCache(false);// XML 二级缓存
        gc.setBaseResultMap(true);// XML ResultMap
        gc.setBaseColumnList(false);// XML columList
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath + "/src/main/java");
        gc.setAuthor("cc");
        gc.setOpen(false);

        // 自定义文件命名，注意 %s 会自动填充表实体属性！
        gc.setMapperName("%sMapper");
        gc.setXmlName("%sMapper");
        gc.setServiceName("%sService");
        gc.setServiceImplName("%sServiceImpl");
        mpg.setGlobalConfig(gc);

        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        // 数据源配置
        dsc.setDbType(DbType.MYSQL);
        dsc.setDriverName("com.mysql.jdbc.Driver");

        dsc.setUrl("jdbc:mysql://127.0.0.1:3306/ssm?characterEncoding=utf8");
        mpg.setDataSource(dsc);

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setTablePrefix(new String[]{"t_"});// 此处可以修改为您的表前缀
//        strategy.setInclude(new String[]{"user"}); // 需要生成的表
//        strategy.setNaming(NamingStrategy.underline_to_camel);// 表名生成策略
//        strategy.setInclude(new String[] { rb.getString("tableName")}); // 需要生成的表
        strategy.setFieldPrefix("c_"); // 去掉字段的前缀
        strategy.setEntityBooleanColumnRemoveIsPrefix(true);
//        strategy.setExclude(new String[]{"t_rong_bid"}); // 排除生成的表
        // 字段名生成策略
        strategy.setNaming(NamingStrategy.underline_to_camel);
        // 自定义实体父类
//         strategy.setSuperEntityClass("hello.entity.BaseEntity");
        // 自定义实体，公共字段
        strategy.setSuperEntityColumns(new String[]{"c_id"});
        // 自定义 mapper 父类
//        strategy.setSuperMapperClass(null);
        // 自定义 service 父类
//        strategy.setSuperServiceClass(null);
        // 自定义 service 实现类父类
        // strategy.setSuperServiceImplClass("com.fcs.demo.TestServiceImpl");
        // 自定义 controller 父类
//         strategy.setSuperControllerClass("com.risk.controller.BaseController");
        mpg.setStrategy(strategy);

        // 包配置
        PackageConfig pc = new PackageConfig();
        // 包配置
        pc.setParent("com.cc");
        pc.setModuleName("ssmDemo");
        pc.setController("controller");
        pc.setEntity("pojo");
        pc.setMapper("mapper");
        mpg.setPackageInfo(pc);
        // 执行生成
        mpg.execute();
    }
}

生成的代码

会自动进行pojo和表的字段映射
