Integration of road SSM learning --spring the next day _spring and junit

the reason:

First, add dependency in pom.xml

Add this dependency, and note the version number to the version number of the same spring-context

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>5.0.2.RELEASE</version>
</dependency>

Add junit dependency, pay attention to where it must be 4.12 or later, or be wrong

<dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>

Second, modify the test class

1, above, was added in the annotation type, attention ContextConfiguration where to add CLASSPATH:
2, class objects automatically injected IAccountService

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:bean.xml")
public class AccountServiceTest {
    @Autowired
    private IAccountService as;
    @Test
    public void testFindAll(){
        List<Account> accounts= as.findAllAccount();
        for (Account account:accounts){
            System.out.println(account);
        }
    }
    @Test
    public void testFindById(){
        Account account = as.findAccountById(1);
        System.out.println(account);
    }
    @Test
    public void testSaveAccount(){
        Account account = new Account();
        account.setName("小新");
        account.setMoney(4000d);
        as.saveAccount(account);
        System.out.println("插入后如下：");
        testFindAll();
    }
    @Test
    public void testUpdateAccount(){
        Account account = as.findAccountById(5);
        account.setMoney(5000d);
        as.updateAccount(account);
        System.out.println("更新后如下：");
        testFindAll();
    }

    @Test
    public void testDeleteAccount(){
        as.deleteAccount(5);
        System.out.println("删除后如下：");
        testFindAll();
    }
}

Record stepped pit

Before also, add maven dependencies and found not reported red, but not actually add in, namely External Libraries under no corresponding package, right-project maven-> reimport there is no reaction, the solution is as follows:
1. Right Project -> open Module settings-> left list Libraries-> delete the wrong package (or simply delete all ctrl + a), then reimport
2, File-> SETTINGS-> Build, Execution, Deployment-> Build Tools-> Maven, check Update snapshots Always
3, see online, is not practical: imi delete files in the project, restart idea
