java Spring SpEL查询是否安全，不受SQL注入攻击？

Question

"#{variable}"Spring表达式语言SpEL值是否安全，不受SQL注入攻击？例如：

@Mapper
public interface UrlInfoMapper {
    public static final String SELECT_BY_ID = "select * from url WHERE ID=#{ID}";
    public static final String DELETE_BY_ID = "DELETE FROM url WHERE ID=#{ID}";

    @Select(SELECT_BY_ID)
    UrlInfo getFromUrlById(String ID);

    @Update(DELETE_BY_ID)
    void delete(@Param("ID")String ID);

我检查了引用，但没有发现被替换为引号等SQL字符的值

https://docs.spring.io/spring/docs/4.3.17.RELEASE/spring-framework-reference/htmlsingle/#expressions

我在网上找不到关于SpEL和SQL注入的内容（只有这个项目没有使用的JPA）

本文讨论的是视图中的SpEL，而不是数据库中的漏洞

我相信是的

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class MockTest {

    @Autowired
    private UserMapper userMapper;

    @Test
    public void sqlInjections() throws Exception {
        User user = userMapper.getUser("admin' ");
        assertNull(user);
    }


@Mapper
public interface UserMapper {

    @Select("select * from user WHERE name =#{name}")
    @Results(value = {
             @Result(property = "name", column = "name"),
             @Result(property = "password", column = "password"),
             @Result(property = "encrypted", column = "encrypted"),
             @Result(property = "permission", column = "permission")
           })
    User getUser(@Param("name")String name);
