今日完成：

1.       .trim()函数去掉字符序列前后空格

2.       ctrl+alt+L自动设置缩进

3.       使用mybatis-generator自动生成，不产生example

4.       spring框架，复习

5.       完成service，controller类，相当于复习

public interface BaseService {

    List<Students> selectStudentsByEvaluate();

    Integer countStudentsByStatus(Integer status);

    List<Profession> selectProfessionByDirection(String direction);

    Salary selectSalaryByPrimaryKey(Integer id);
}

@Service
public class SchoolService implements BaseService {

    @Autowired
    private StudentsMapper studentsMapper;

    @Autowired
    private ProfessionMapper professionMapper;

    @Autowired
    private SalaryMapper salaryMapper;

    public List<Students> selectStudentsByEvaluate() {
        List<Students> list = studentsMapper.selectByEvaluate();
        return list;
    }

    public Integer countStudentsByStatus(Integer status) {
        Integer num = studentsMapper.countByStatus(status);
        return num;
    }

    public List<Profession> selectProfessionByDirection(String direction) {
        List<Profession> list = professionMapper.selectByDirection(direction);
        return list;
    }

    public Salary selectSalaryByPrimaryKey(Integer id) {
        Salary salary = salaryMapper.selectByPrimaryKey(id);
        return salary;
    }
}

6.       将html页面转换为jsp页面

静态文件

<mvc:resources mapping="/css/**" location="/WEB-INF/statics/css/"/>
<mvc:resources mapping="/js/**" location="/WEB-INF/statics/js/"/>
<mvc:resources mapping="/image/**" location="/WEB-INF/statics/image/"/>

forEach循环在jsp页面显示优秀学员

<c:forEach items="${students}" var="s">

    <li class="col-xs-12 col-sm-6 col-md-6 col-lg-3">
    <div>
    <img src="/image/${s.picture}">
    <span>${s.profession}:${s.name}</span>
    <p class="text-left">${s.job}：${s.workIntroduction}</p>
    </div>
    </li>

</c:forEach>

替换人数

<p>
    <img src="/image/453254312.png">${count}<br>
    <span class="up-3">累计在线学习人数</span>
</p>
<p>
    <img src="/image/453254312.png">${graduated}<br>
    <span class="up-3">学员已经找到满意工作</span>
</p>

效果

明日计划：

1.       完成任务四

遇到的问题:

1.       在spring中配置basePackage后是不是DAO已经成为一个bean存在于spring中了，不需要使用@Repository注解？

收获：

1.       将html页面转化为jsp页面从数据库中读取数据

2.       springmvc中静态文件处理

3.       复习构造一个完整的springmvc框架
