我有一个看起来像这样的课程
public User createUser(User user, Set<UserRole> userRoles) throws DataAccessException {
User localUser = userRepository.findByUsername(user.getUsername());
if (localUser != null) {
LOG.info("user {} already exists. Nothing will be done.", user.getUsername());
} else {
for (UserRole ur : userRoles) {
roleRepository.save(ur.getRole());
}
user.getUserRoles().addAll(userRoles);
localUser = userRepository.save(user);
}
我正在编写一个单元测试，顺便说一下我的存储库被嘲笑但不会包含在问题中，我一直在收到错误
UserRepository.findByUsername(null)
Usage is: expect(a.foo()).andXXX(), mergedContextConfiguration = [WebMergedContextConfiguration@6963b0bd testClass = LogicTest, locations = '{}', classes = '{class com.adminportal.config.SecurityConfig}', contextInitializerClasses = '[]', activeProfiles = '{}', propertySourceLocations = '{}', propertySourceProperties = '{}', contextCustomizers = set[org.springframework.test.context.web.socket.MockServerContainerContextCustomizer@48524010, org.springframework.boot.test.context.filter.ExcludeFilterContextCustomizer@5906ebcb, org.springframework.boot.test.json.DuplicateJsonObjectContextCustomizerFactory$DuplicateJsonObjectContextCustomizer@55a561cf, org.springframework.boot.test.mock.mockito.MockitoContextCustomizer@0, org.springframework.boot.test.autoconfigure.properties.PropertyMappingContextCustomizer@0, org.springframework.boot.test.autoconfigure.web.servlet.WebDriverContextCustomizerFactory$Customizer@2cbb3d47], resourceBasePath = 'src/main/webapp', contextLoader = 'org.springframework.test.context.web.WebDelegatingSmartContextLoader', parent = [null]]].
这是测试，有人可以告诉我，我认为从存储库调用获取用户名
是错误的吗？ @Test
public void createUserTest() throws Exception {
User user1 = new User();
user1.setUsername("james");
User user = userRepository.findByUsername(user1.getUsername());
Set<UserRole> userRoles = new HashSet<>();
Role role1 = new Role();
role1.setRoleId(3);
role1.setName("ADMIN");
userRoles.add(new UserRole(user1, role1));
userRepository.save(user1);//stack trace show problem with this line
expect(user1.getUsername()).andReturn("james");
}
谢谢 堆栈跟踪
