主要目的：實現JUnit的Crud
專案目前情況：spring+mybatis
想在前後端分離的情況下，
後端實現各個模組CRUD的junit
遇到的最大問題先是注入之後提示nullPointException
接著很快反應過來
是junit執行單個檔案的時候並沒有在啟動容器，也就是說單獨執行一個檔案沒有初始化spring，也就無法使用service了
那麼如何才能初始化spring呢？這就是這次junit中遇到的最大的問題

public static ProjectService projectService;

   @Autowired
   public static ProjectService projectService;
    @BeforeClass
    public static void init() {//junit之前init spring
        ApplicationContext   context = new ClassPathXmlApplicationContext("classpath*:conf/root.xml");//這裡路徑之前沒有配對於是一直出錯
        projectService = (ProjectService)context.getBean("projectService");
    }

        project.setPrealendDate(new Date());//實際回款日期
        project.setRemark("測試資料");
        project.setStateCode("0");
        projectService.insertProject(project);
        projectService.updateProject(project);

    }

    public static void main(String[] args){
        try {
         //   addProject();
        } catch (Exception e) {
            System.out.println("---------------------新增錯誤--------------------");
            e.printStackTrace();
        }
    }
    public Map<String, String> SELECT1(Map<String, String> b) {
        return b;
    }

    // @Test
    public static Map<String, Project> JSON2Map() {
        System.out.println("shuchu");
        Map<String, Project> map = new HashMap<String, Project>();
        return map;
    }
}

上面程式碼中的
ApplicationContext context = new ClassPathXmlApplicationContext(“classpath*:conf/root.xml”);//
大家一定覺得好奇了，因為我們的配置檔案肯定不止一個，如何把spirng和spring-mvc以及其他xml引入呢？
這個時候就需要寫一個類似web.xml的檔案包含所有需要的配置檔案了
即：root.xml

接著spring的初始化就算完成了
接著是測試mapping的crud
首先是測試insert

第一部分是基本配置
<mapper namespace="project.dao.ProjectDao">


    <!--表名 -->
    <sql id="table_name">project</sql>

    <sql id="table_roles">staff_roles</sql>

    <sql id="select_fields">
               project_name,project_code, project_type, interest_date,interest_ratio,company_id,
                company_name,linkman_id,linkman_name,create_id,creater_name,budget_income,
                budget_expenses,real_expenses,create_date,edit_date,
               pstart_date, pfull_date,pvalue_date,pend_date,prealend_date,remark,state_code
    </sql>
    <resultMap id="entityMap" type="project.domain.Project">
        <result column="project_name" property="projectName"  />
        <result column="project_code" property="projectCode" />
        <result column="project_type" property="projectType" />
        <result column="interest_date" property="interestDate" />
        <result column="interest_ratio" property="interestRatio" />
        <result column="company_id" property="companyId" />
        <result column="company_name" property="companyName"  />
        <result column="linkman_id" property="linkmanId" />
        <result column="linkman_name" property="linkmanName" />
        <result column="create_id" property="createId" />
        <result column="creater_name" property="createrName" />
        <result column="budget_income" property="budgetIncome" />
        <result column="budget_expenses" property="budgetExpenses" />
        <result column="real_expenses" property="realExpenses" />
        <result column="create_date" property="createDate"  />
        <result column="edit_date" property="editDate" />
        <result column="pstart_date" property="updatedAt" />
        <result column="pfull_date" property="operatorId" />
        <result column="pvalue_date" property="pvalueDate" />
        <result column="pend_date" property="pendDate"  />
        <result column="prealend_date" property="prealendDate" />
        <result column="remark" property="remark" />
        <result column="state_code" property="stateCode" />
    </resultMap>

第二部分是CRUD模組的實現
    <!--新增-->
    <!--keyProperty：指主鍵屬性名，也是返回的資料
    useGeneratedKeys：表示設定是否使用JDBC的getGenereatedKeys方法獲取主鍵並賦值到keyProperty設定的領域模型屬性中->
    <insert id="insertProject" parameterType="project.domain.Project" keyColumn="project_id" useGeneratedKeys="true" keyProperty="project_id">
        INSERT INTO
        <include refid="table_name"></include>
        (
        <include refid="select_fields" />
        )
        VALUES
        (
        #{projectName},#{projectCode},#{projectType},#{interestDate},#{interestRatio},#{companyId},
        #{companyName},#{linkmanId},#{linkmanName},#{createId},#{createrName},#{budgetIncome},
        #{budgetExpenses},#{realExpenses},#{createDate},#{editDate},
        #{pstartDate},#{pfullDate},#{pvalueDate}, #{pendDate}, #{prealendDate},#{remark},
        #{stateCode}
        )
    </insert>

最後測試結果（如下）新增成功，但是部分欄位未儲存成功，資料丟失問題，有空繼續補全
