Controller


package com.boda.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.boda.model.Department;
import com.boda.service.DepartmentService;

@Controller
public class DepartmentController {

	@Autowired
	private DepartmentService departmentService;

	@RequestMapping(value = "department.do")
	public String create() throws Exception{
		return "welcome";
	}
}

报错信息


javax.servlet.ServletException: Could not resolve view with name 'welcome' in servlet with name 'SampleSpringMVC'
	org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1029)
	org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:817)

解决办法过滤所有请求<url-pattern>/</url-pattern>
Controller改为如下


package com.boda.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.boda.model.Department;
import com.boda.service.DepartmentService;

@Controller
@RequestMapping(value = "hr/department/")
public class DepartmentController {

	@Autowired
	private DepartmentService departmentService;

	@RequestMapping(value = "add")
	public String create() throws Exception{
		return "hr/welcome";
	}
}
