第二步 创建ssm_pojo子模块（mybatis逆向这里不做赘述，直接将生成好的复制即可）

创建实体类TbBrand实体类

package com.itcode.pojo;
 
import java.io.Serializable;
 
public class TbBrand implements Serializable {
  private Long id;
 
  private String name;
 
  private String firstChar;
  
  //此处省略get/set方法以及toString方法

创建TbBrandExample条件类 

package com.itcode.pojo;
 
import java.util.ArrayList;
import java.util.List;
 
public class TbBrandExample {
  protected String orderByClause;
 
  protected boolean distinct;
 
  protected List<Criteria> oredCriteria;
 
  public TbBrandExample() {
    oredCriteria = new ArrayList<Criteria>();
  }
 
  public void setOrderByClause(String orderByClause) {
    this.orderByClause = orderByClause;
  }
 
  public String getOrderByClause() {
    return orderByClause;
  }
 
  public void setDistinct(boolean distinct) {
    this.distinct = distinct;
  }
 
  public boolean isDistinct() {
    return distinct;
  }
 
  public List<Criteria> getOredCriteria() {
    return oredCriteria;
  }
 
  public void or(Criteria criteria) {
    oredCriteria.add(criteria);
  }
 
  public Criteria or() {
    Criteria criteria = createCriteriaInternal();
    oredCriteria.add(criteria);
    return criteria;
  }
 
  public Criteria createCriteria() {
    Criteria criteria = createCriteriaInternal();
    if (oredCriteria.size() == 0) {
      oredCriteria.add(criteria);
    }
    return criteria;
  }
 
  protected Criteria createCriteriaInternal() {
    Criteria criteria = new Criteria();
    return criteria;
  }
 
  public void clear() {
    oredCriteria.clear();
    orderByClause = null;
    distinct = false;
  }
 
  protected abstract static class GeneratedCriteria {
    protected List<Criterion> criteria;
 
    protected GeneratedCriteria() {
      super();

      }
      criteria.add(new Criterion(condition, value));
    }
 
    protected void addCriterion(String condition, Object value1, Object value2, String property) {
      if (value1 == null || value2 == null) {
        throw new RuntimeException("Between values for " + property + " cannot be null");
      }
      criteria.add(new Criterion(condition, value1, value2));
    }
 
    public Criteria andIdIsNull() {
      addCriterion("id is null");
      return (Criteria) this;
    }
 
    public Criteria andIdIsNotNull() {
      addCriterion("id is not null");

      return (Criteria) this;
    }
 
    public Criteria andNameLessThanOrEqualTo(String value) {

      return (Criteria) this;
    }
 
    public Criteria andNameLike(String value) {
      addCriterion("name like", value, "name");
      return (Criteria) this;
    }
 
    public Criteria andNameNotLike(String value) {
      addCriterion("name not like", value, "name");
      return (Criteria) this;

    public Criteria andFirstCharIsNull() {

      return (Criteria) this;
    }
 
    public Criteria andFirstCharNotBetween(String value1, String value2) {
      addCriterion("first_char not between", value1, value2, "firstChar");
      return (Criteria) this;
    }
  }
 
  public static class Criteria extends GeneratedCriteria {
 
    protected Criteria() {
      super();
    }
  }
 
  public static class Criterion {
    private String condition;
 
    private Object value;
 
    private Object secondValue;
 
    private boolean noValue;
 
    private boolean singleValue;
 
    private boolean betweenValue;
 
    private boolean listValue;
 
    private String typeHandler;
 
    public String getCondition() {
      return condition;
    }
 
    public Object getValue() {
      return value;
    }
 
    public Object getSecondValue() {
      return secondValue;
    }
 
    public boolean isNoValue() {
      return noValue;
    }
 
    public boolean isSingleValue() {
      return singleValue;
    }
 
    public boolean isBetweenValue() {
      return betweenValue;
    }
 
    public boolean isListValue() {
      return listValue;
    }
 
    public String getTypeHandler() {
      return typeHandler;
    }
 
    protected Criterion(String condition) {
      super();
      this.condition = condition;
      this.typeHandler = null;
      this.noValue = true;
    }
 
    protected Criterion(String condition, Object value, String typeHandler) {
      super();
      this.condition = condition;
      this.value = value;
      this.typeHandler = typeHandler;
      if (value instanceof List<?>) {
        this.listValue = true;
      } else {
        this.singleValue = true;
      }
    }
 
    protected Criterion(String condition, Object value) {
      this(condition, value, null);
    }
 
    protected Criterion(String condition, Object value, Object secondValue, String typeHandler) {
      super();
      this.condition = condition;
      this.value = value;
      this.secondValue = secondValue;
      this.typeHandler = typeHandler;
      this.betweenValue = true;
    }
 
    protected Criterion(String condition, Object value, Object secondValue) {
      this(condition, value, secondValue, null);
    }
  }
}

创建一个Result返回通知类

package com.itcode.pojo;
 
import java.io.Serializable;
 
 
public class Result implements Serializable {
  private boolean success; //判断该变量
  private String message; //返回的字符串
 
  public Result(boolean success, String message) {
    this.success = success;
    this.message = message;
  }
  //此处省略get/set方法，自行补全

第三步 创建ssm_dao子模块（逆向工程也可以生成）

创建TbBrandMapper接口类

package com.itcode.dao;
 
import com.itcode.pojo.TbBrand;
import com.itcode.pojo.TbBrandExample;
import org.apache.ibatis.annotations.Param;
 
import java.util.List;
import java.util.Map;
 
public interface TbBrandMapper {
  int countByExample(TbBrandExample example);
 
  int deleteByExample(TbBrandExample example);
 
  int deleteByPrimaryKey(Long id);
 
  int insert(TbBrand record);
 
  int insertSelective(TbBrand record);
 
  List<TbBrand> selectByExample(TbBrandExample example);
 
  TbBrand selectByPrimaryKey(Long id);
 
  int updateByExampleSelective(@Param("record") TbBrand record, @Param("example") TbBrandExample example);
 
  int updateByExample(@Param("record") TbBrand record, @Param("example") TbBrandExample example);
 
  int updateByPrimaryKeySelective(TbBrand record);
 
  int updateByPrimaryKey(TbBrand record);
 
  List<Map> selectOptionList();
}

创建TbBrandMapper.xml文件

 </update>
 <select id="selectOptionList" resultType="java.util.Map">
   select id,name as text from tb_brand
 </select>
 
</mapper>

第四步 创建ssm_service子模块

创建一个service接口

package com.itcode.service;
 
import com.itcode.pojo.TbBrand;
 
import java.util.List;
 
public interface BrandService {
  List<TbBrand> findAll();
 
  void insert(TbBrand brand);
}

创建一个service的实现类

package com.itcode.service.impl;
 
import com.itcode.dao.TbBrandMapper;
import com.itcode.pojo.TbBrand;
import com.itcode.service.BrandService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
 
import java.util.List;
 
@Service
@Transactional
public class BrandServiceImpl implements BrandService {
  @Autowired
  private TbBrandMapper tbBrandDao;
  @Override
  public List<TbBrand> findAll() {
    return tbBrandDao.selectByExample(null);
  }
 
  @Override
  public void insert(TbBrand brand) {
    tbBrandDao.insert(brand);
  }
}

jdbc.properties配置（在resource中配置）

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/数据库名?characterEncoding=utf-8
jdbc.username=用户名
jdbc.password=密码

applicationContext.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">
 
  <!--1.注解扫描: 只扫描service包。-->
  <context:component-scan base-package="com.itcode.service"/>
 
  <!--2. 加载properties-->
  <context:property-placeholder location="classpath:jdbc.properties"/>
 
  <!--3. 创建连接池-->
  <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
    <property name="driverClassName" value="${jdbc.driver}"/>
    <property name="url" value="${jdbc.url}"/>
    <property name="username" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
  </bean>
 
  <!--4. Spring整合Mybatis：把SqlSessionFactory对象的创建交给Spring完成-->
  <bean class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <!--<property name="mapperLocations" value="classpath:com/itcode/dao/TbBrandMapper.xml"/>-->
  </bean>
 
  <!--5. 扫描dao的接口所在包，自动对该包下所有的dao接口自动生成代理对象-->
  <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.itcode.dao"/>
  </bean>
 
  <!--6. 事务管理器 -->
  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
  </bean>
 
  <!--7. 开启事务控制的注解支持 -->
  <tx:annotation-driven transaction-manager="transactionManager"/>
 
  <!--以下配置请忽略只是为了回顾用-->
  <!--此处是第二种方式 Spring声明式事务管理配置-->
  <!--6.1 事务管理器
  <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
  </bean>
   6.2 事务通知规则
  <tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
      <tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
      <tx:method name="*" propagation="REQUIRED" read-only="false"/>
    </tx:attributes>
  </tx:advice>
   6.3 Aop配置 = 切入点表达式 + 通知规则的引用
  <aop:config>
    <aop:pointcut id="pt" expression="execution(* com..*ServiceImpl.*(..))"/>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
  </aop:config>  -->
</beans>

第五步 创建一个ssm_web子模块

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://java.sun.com/xml/ns/javaee"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
  http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
     version="2.5">
 
  <!-- 解决post乱码 -->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>utf-8</param-value>
    </init-param>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
 
  <!--SpringMVC前端控制器-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springMVC.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
 
  <!--配置监听器，加载applicationContext.xml配置文件-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
</web-app>

springMVC.xml配置说明

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
 
  <!--1. 注解扫描： 之扫描controller包下的注解-->
  <context:component-scan base-package="com.itcode.controller"/>
 
  <!--2. 注解驱动,controller返回值支持json-->
  <mvc:annotation-driven>
    <mvc:message-converters register-defaults="true">
      <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
        <property name="supportedMediaTypes" value="application/json"/>
        <property name="features">
          <array>
            <value>WriteMapNullValue</value>
            <value>WriteDateUseDateFormat</value>
          </array>
        </property>
      </bean>
    </mvc:message-converters>
  </mvc:annotation-driven>
</beans>

创建一个BrandController类

package com.itcode.controller; 
import com.itcode.pojo.Result;
import com.itcode.pojo.TbBrand;
import com.itcode.service.BrandService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
import java.util.List;
 
@RestController
@RequestMapping("/brand")
public class BrandController {
 
  @Autowired
  private BrandService brandService;
 
  @RequestMapping("/findAll")
  public List<TbBrand> findAll(){
    return brandService.findAll();
  }
 
  @RequestMapping("/insert")
  public Result insert(@RequestBody TbBrand brand){
    try {
      brandService.insert(brand);
      return new Result(true, "新增成功");
    } catch (Exception e) {
      e.printStackTrace();
      return new Result(false, "新增失败");
    }
  }
}

最后配置一下tomcat，启动tomcat可以了，如果想要测试我们的接口可以使用Postman进行测试。
