Java spring 测试表单端点
Java spring test form endpoint
我想创建测试来测试我的插入表单端点。问题是当我 运行 测试给我这个错误 - java.lang.NullPointerException at com.zetcode.integrationTest.Test2.testRegistration(Test2.java:52)
这是我的端点
Controller
public class CreateAccountUserController {
@RequestMapping(value = "/CreateUserAccount", method = RequestMethod.POST)
public String createAccount(
@RequestParam(value = "fullName", required = false) String fullName,
@RequestParam(value = "email", required = false) String email,
@RequestParam(value = "username", required = false) String username,
@RequestParam(value = "password", required = false) String password,
Model model,

DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
dataSource.setUsername("mssqllogin");

dataSource.setUrl("jdbc:sqlserver://localhost\SQLEXPRESS:1433;databaseName=AdminToolWeb");
try {

emp.setPassword(td.encrypt(emp.getPassword()));
Connection connection2 = dataSource.getConnection();
PreparedStatement st = connection2.prepareStatement(

} catch (Exception e) {

这是我的 html 表格
